Gaming Glossary

Triple-A (AAA) is an informal industry term designating games produced and marketed with the largest budgets in the industry, typically by major publishing conglomerates — Activision Blizzard (Microsoft), Electronic Arts, Ubisoft, Sony Interactive Entertainment, Xbox Game Studios — or large independent studios with equivalent resources. AAA games typically feature large development teams (200–1000+ developers across multiple studios), production values comparable to Hollywood blockbusters (motion capture, orchestral scores, celebrity voice acting), massive marketing campaigns, and retail pricing at the highest tier ($70 on current generation consoles). Examples include Call of Duty, FIFA/EA Sports FC, Assassin's Creed, God of War, and The Last of Us. The AAA designation does not guarantee quality — it reflects budget and production scale, not creative success. The model has faced structural criticism: rising development budgets demand risk-averse design targeting the broadest audiences; sequels and franchise iterations are safer investments than original IP; and long development cycles (5–7 years) make it difficult to respond to market shifts. Development costs have escalated to the point where even critically acclaimed AAA games must sell 10–15 million copies to break even, creating industry-wide anxiety about sustainability. The 2023 wave of industry layoffs — affecting tens of thousands of workers at major publishers — reflected the financial pressure of AAA economics.

A genre that blends real-time action combat — where the player directly controls attacks, dodges, and abilities in real time — with RPG progression systems such as character levelling, skill trees, loot-driven equipment upgrades, and stat allocation. The player's mechanical skill matters alongside their character build, distinguishing ARPGs from traditional turn-based RPGs where strategy matters more than reflex. The genre divides broadly into two visual styles: the isometric hack-and-slash ARPG (Diablo, Path of Exile, Torchlight, Last Epoch), which emphasises loot density and build optimization; and the third-person narrative ARPG (The Witcher 3, Elden Ring, Baldur's Gate 3's combat mode), which emphasises world-building and story alongside combat depth. Diablo (1996) and its sequels established the loot loop that became the isometric ARPG standard, while FromSoftware's games created the soulslike ARPG branch. The genre dominates modern mainstream gaming: in any year, the biggest titles are almost always ARPGs or genres directly adjacent to them. A common criticism of ARPGs is 'gear treadmill' design — content exists primarily to deliver better numbers rather than meaningfully different gameplay.

A seasonal progression system in which players purchase (or sometimes earn through play) access to a tiered reward track containing cosmetics, currency, and experience boosts, then unlock those rewards by completing in-game challenges or accumulating playtime experience over the course of a season — typically 60 to 90 days. Battle passes were introduced to PC gaming by Dota 2 in 2013 but became the dominant live-service monetisation model after Fortnite's Chapter 1, Season 2 pass (2018) proved the formula could generate enormous recurring revenue at accessible price points ($10 per season). The model offers structural advantages over loot boxes: players know exactly what they are buying (no randomness), the content scales with engagement (active players get more value), and the time-limited nature creates seasonal events with clear beginnings and endings. Criticism of battle passes centres on their time-demand engineering — daily and weekly challenges are designed to create habitual login patterns, and missing a season's content can never be recovered — as well as the accumulation of cosmetics players may never use. A significant design evolution came when Fortnite introduced a 'never expire' clause for battle pass content, acknowledging that expiry-pressure is a meaningful source of player anxiety. Premium battle passes now offer an alternative to loot boxes in many major titles including Apex Legends, Call of Duty, and Valorant.

A multiplayer game genre in which a large number of players — typically 60 to 150 — are dropped onto a large map with no equipment, scavenge for weapons and armour, and fight to be the last player or squad standing. A defining mechanical feature is the shrinking play zone: an ever-tightening safe area (often represented as a circle or storm) forces players who would otherwise hide to continuously move toward each other, guaranteeing escalating confrontation as the match progresses. The genre takes its name from the 2000 Japanese film Battle Royale (and indirectly the 1999 novel by Koushun Takami). PlayerUnknown's Battlegrounds (PUBG, 2017) established the modern template and sold 75 million copies; Fortnite (Epic Games, 2017) made the genre a global cultural phenomenon by adding building mechanics and free-to-play. Today's major battle royales include Apex Legends (hero-based abilities), Warzone (military realism), and the mobile-dominant BGMI and Free Fire. The genre demands a combination of looting efficiency, combat aim, and positioning strategy — players who understand the final safe zones and manage their rotations consistently outperform purely aim-focused players. Squad-based modes (duos, trios, quads) have become dominant because they reduce the pressure of solo play.

Cooperative gameplay in which two or more players work together toward shared objectives rather than competing against each other, with success and failure shared collectively. Co-op modes range widely in structure: split-screen couch co-op (It Takes Two, Overcooked) where players share a screen in the same room; online co-op campaigns (Deep Rock Galactic, Halo, Sea of Thieves) where players tackle missions together online; raid groups in MMORPGs requiring coordinated teams of 8–40 players; and asymmetric co-op where players have different roles or mechanics (Keep Talking and Nobody Explodes). Co-op gaming experienced a major resurgence in the early 2020s with Deep Rock Galactic, Valheim, Phasmophobia, and Lethal Company proving that the social experience of shared struggle and coordinated problem-solving drives deep engagement and word-of-mouth growth. It Takes Two (2021) won Game of the Year at multiple ceremonies and is broadly considered one of the best co-op games ever made. A distinct branch is 'asynchronous co-op,' where players contribute to a shared world at different times — Palworld's shared server base-building exemplifies this. The rise of cross-play has dramatically expanded co-op's reach by removing platform barriers between friends.

Cross-platform multiplayer — the technical and commercial capability for players on different hardware platforms (PC, PlayStation 5, Xbox Series X|S, Nintendo Switch, iOS, Android) to compete or cooperate in the same online game sessions. Crossplay was a contested feature for most of gaming's online history: platform holders — primarily Sony — resisted it because platform-exclusive player pools created lock-in incentives and prevented player migration. Epic Games used Fortnite's cultural dominance to force crossplay adoption from Sony in 2018, establishing a precedent that has since become expected for major multiplayer titles. Rocket League, Apex Legends, Call of Duty, Minecraft, and most major live-service games now offer full crossplay. The benefits are significant: a unified player pool dramatically improves matchmaking quality and reduces queue times, and friends on different platforms can play together without purchasing duplicate hardware. Critics point to PC players' mechanical advantage over controller players in fast-paced shooters — mouse and keyboard precision is demonstrably superior for aiming in FPS games — which has led many games to implement separate crossplay opt-in settings allowing players to restrict their matches to same-input-method pools. Cross-progression (sharing save data, purchased cosmetics, and unlocks across platforms) is a separate feature from crossplay and has been implemented more slowly, as it conflicts with platform holder revenue from separate storefronts.

A period of mandatory or culturally enforced extreme overtime worked by game developers — typically in the months before a game's release date or major milestone — characterised by 60–100 hour work weeks, suppressed personal time, and sustained high-pressure output. Crunch is systemic in AAA game development and has been widely documented through investigative reporting and developer testimonials at studios including Rockstar Games (100-hour weeks during Red Dead Redemption 2 development, confirmed by a co-founder's blog post that generated significant industry backlash), CD Projekt Red (mandatory six-day work weeks before Cyberpunk 2077's launch), Naughty Dog, Epic Games, and Ubisoft. The practice results in burnout, health deterioration, relationship breakdown, and departure of experienced developers who can no longer sustain the pace — creating a brain drain that ironically degrades the very product crunch is intended to complete. The root causes are multi-layered: unrealistic publisher release commitments, poor project management, scope expansion without timeline adjustment, and a culture that frames overwork as passion rather than exploitation. The games industry has faced increasing union organising in response to crunch and related labour issues — the Communications Workers of America (CWA) has organised at Activision Blizzard, ZeniMax, and other studios. Some studios have committed to no-crunch policies; whether they hold through release pressure is subject to ongoing scrutiny.

A software update released simultaneously with a game's retail launch — or available for pre-load before launch day — that applies fixes, performance improvements, and content additions to the version shipped on physical media. Day-one patches became a standard industry practice as always-online console infrastructure (Xbox Live, PlayStation Network) made post-manufacture updates trivially distributable from the early 2000s onward. They are sometimes controversial when very large: Cyberpunk 2077's day-one patch was 43 GB on console, suggesting the disc version was substantially incomplete. Halo: The Master Chief Collection's launch issues despite a substantial day-one patch highlighted that patching is not a guarantee of a working product. Day-one patches are usually necessary because the certification and manufacturing process for physical disc distribution takes 4–8 weeks, during which developers continue finding and fixing bugs. The patch content ranges from critical crash fixes (applied without announcement) to new content that couldn't be included on the disc (the 'day-one DLC' controversy, where content finished before launch is sold separately rather than included). For digital-only purchases, the distinction between 'day-one patch' and 'version 1.01' is largely semantic — both represent post-build development applied before the player experiences the game.

Downloadable Content — additional content for a released game sold separately from the base game, distributed digitally and downloaded by the player. DLC covers a wide spectrum: small cosmetic packs (character skins, weapon wraps) at the low end; mid-tier content packs (new maps, new character story missions); and large paid expansions that add entire new game areas, storylines, and mechanics comparable in scope to standalone titles at the high end. Elden Ring: Shadow of the Erdtree (2024) and The Witcher 3: Blood and Wine are examples of expansion-scale DLC that are among the best content in their respective games, setting a high bar for what DLC can be. Season passes bundle multiple planned DLC releases at a discounted upfront price — a model that requires trust in the developer's future plans and fell out of favour as battle pass models provided more flexible monetisation. DLC has been a point of industry controversy when content appears to have been deliberately removed from the base game to create a paid upsell — a practice associated with Capcom's disc-locked content era (2011–2012) where DLC data was already on the purchased disc. Most publishers now distinguish clearly between paid narrative expansions (legitimate DLC) and cosmetic shops or battle passes (live-service monetisation), though the line between them remains contested.

Competing spatial upscaling and frame generation technologies that allow games to render at a lower internal resolution while reconstructing a visually comparable higher-resolution output, recovering GPU performance lost to demanding settings like ray tracing or 4K rendering. DLSS (Deep Learning Super Sampling), developed by NVIDIA, uses a neural network trained on ultra-high-resolution reference frames to produce upscaled images with quality superior to simple bilinear or bicubic scaling, particularly in motion and fine detail. DLSS is exclusive to NVIDIA RTX GPUs. FSR (FidelityFX Super Resolution), developed by AMD and open-source, uses a spatial upscaling algorithm without machine learning, making it compatible with virtually any GPU — including NVIDIA cards — and requires no AI training data. FSR 4 (2025) introduced machine-learning upscaling competitive with DLSS, though limited to RDNA4 GPUs initially. Intel's XeSS offers a third option optimised for Arc GPUs. Frame Generation, available in DLSS 3 and FSR 3, synthesises additional frames between rendered frames to multiply perceived frame rates — useful for high-performance targets but not recommended for fast-paced competitive games due to latency implications. In practice, DLSS Quality and FSR Quality modes typically add minimal visual degradation while recovering 30–70% of GPU performance, making them near-mandatory settings for ray tracing at high resolutions.

A game release model in which players can purchase and play an incomplete game while the developer continues active development — adding content, balancing systems, and fixing issues based partly on community feedback — before the game reaches its 1.0 'full release.' Steam's Early Access program, formalised in 2013, gave the model its most visible platform and standard expectations. When it works well, Early Access creates a symbiotic relationship: developers get funding and real-player feedback during development; players get early access to a game they're excited about and the experience of shaping its direction. Hades, Deep Rock Galactic, and Satisfactory are widely cited examples of Early Access done right — all exited to critically acclaimed full releases after years of substantive updates. When it fails, Early Access becomes a model for selling unfinished games with no accountability for completion: some games have remained in Early Access for over a decade without approaching a full release. Buyers should research developer track records (have they shipped before?), community health (are recent reviews positive?), and update frequency before purchasing Early Access titles. The 'survival craft' genre is particularly dense with Early Access titles — games like Valheim, Subnautica, and 7 Days to Die found massive success, while hundreds of similar titles released and silently abandoned development.

Organized competitive gaming at professional and semi-professional levels, structured around dedicated teams, coaching staff, regular league seasons, and major international tournaments with substantial prize pools and media rights. Esports encompasses spectator events watched by millions, professional player contracts, team ownership by investors and traditional sports franchises, and broadcast deals with streaming platforms and cable networks. The industry traces formal roots to the Cyberathlete Professional League (CPL, 1997) and South Korea's StarCraft: Brood War professional scene (late 1990s), where cable television broadcast matches to national audiences and players became celebrities. Modern esports are anchored by five dominant titles: League of Legends (Worlds tournament, $2M+ prize pool), Dota 2 (The International, highest prize pools in esports history — $40M in 2021), Counter-Strike 2 (CS Major Championships), Valorant (Champions Tour), and PUBG/Free Fire on mobile in Southeast Asia. Total esports viewership reached 532 million globally in 2022 according to Newzoo. The esports industry has faced structural challenges including team profitability, player career longevity (peak performance typically ages 18–25), and viewer growth plateauing after the pandemic-era surge. College esports programs have grown significantly as a pipeline for talent and a legitimisation pathway.

First-Person Shooter — a genre of action game where the player experiences gameplay from the protagonist's first-person perspective, seeing through the character's eyes, and where shooting mechanics are the primary mode of interaction. The genre began with Wolfenstein 3D (1992) and was codified by Doom (1993) and Quake (1996), both id Software titles that established the template for 3D movement, weapons, and level design. The genre divides into several distinct sub-categories: arena shooters (Quake, Unreal Tournament) emphasise mechanical skill and fast movement; military realistic shooters (Call of Duty, Battlefield) prioritise tactical positioning and gunplay feel; hero shooters (Valorant, Overwatch 2) add distinctive character abilities to the formula; and immersive sims (Bioshock, Dishonored) blend FPS combat with RPG systems and environmental storytelling. The FPS genre is the most popular in competitive gaming and esports: Counter-Strike 2, Valorant, and Overwatch 2 command massive tournament ecosystems and professional leagues. Key skills in FPS games include aim precision, crosshair placement, map awareness, and game sense — understanding where enemies are likely to be before you see them. Modern FPS titles extensively use aim-assist on controllers to help console players compete with mouse-and-keyboard accuracy.

Precise numerical properties describing the timing characteristics of every move in a fighting game, measured in video frames (typically at 60fps, so 1 frame = 16.7ms). Frame data comprises three core components: startup frames (how many frames after input before the attack hitbox becomes active, determining how quickly you can interrupt or beat an opponent); active frames (how many frames the hitbox remains active, determining the move's threat window); and recovery frames (how many frames the character remains committed to the animation after the attack ends, determining vulnerability to counter-attack). Derived concepts include 'on hit advantage' (if the move connects and hits the opponent, how many frames ahead or behind you are) and 'on block advantage' (if the opponent blocks the move, how many frames ahead or behind you are). A move that is -5 on block means the opponent has a 5-frame advantage after blocking it — if they have a 4-frame startup normal, they can punish you; if their fastest move is 6 frames, you're safe. Mastery of frame data allows competitive players to construct 'punishable on block' knowledge (which moves they can respond to), 'safe pressure' sequences (attacks that cannot be reversal-punished), and meaty setups (timing active frames to coincide with the opponent's wakeup). Most modern fighting games display frame data in training mode directly, removing the need for external resources — Street Fighter 6 and Tekken 8 both feature built-in frame data display.

A game distribution model in which the base game is available at no monetary cost, with the developer's revenue generated entirely through optional in-game purchases — cosmetics, battle passes, character unlocks, or in some cases gameplay-affecting items (pay-to-win). Abbreviated F2P. Free-to-play has dominated mobile gaming since the smartphone era began and expanded aggressively to PC and console following Fortnite's 2017 success: in competitive gaming, F2P titles can reach player counts orders of magnitude higher than equivalent premium games because the zero-cost barrier to entry maximises the potential audience. Fortnite, Apex Legends, Warzone, League of Legends, Dota 2, Valorant, and Path of Exile are all free-to-play and collectively among the most-played games in the world. The F2P model creates specific design challenges: if a game is too easy for non-payers, revenue suffers; if it's too hard, players churn. The healthiest F2P games (League of Legends, Fortnite) monetise purely cosmetically while keeping all gameplay systems accessible regardless of spending. The most criticised F2P designs use artificial friction — energy timers, stamina systems, upgrade bottlenecks — that spending can bypass, creating the pay-to-win dynamic that competitive players find toxic. F2P mobile games frequently use dark patterns including fake timers, misleading probability displays, and social pressure mechanics to drive spending beyond player intentions.

A monetisation mechanic in which players spend currency — real money converted to premium in-game currency — for randomised draws that yield characters, weapons, or cosmetics at variable rarity rates, modelled on Japanese gashapon capsule toy vending machines. The mechanic originated in Japanese mobile gaming and was brought to global prominence by Fate/Grand Order (2015) and most dramatically by Genshin Impact (2020), which demonstrated that gacha could generate billions annually in a production-quality open-world RPG. Key gacha concepts include: the 'pity system' — a guaranteed high-rarity reward after a set number of pulls, typically 90 in Genshin Impact; 'rate-up banners' that increase the probability of a specific limited character; and 'soft pity,' where pull rates increase gradually before the hard pity threshold. Gacha mechanics have been subject to regulatory scrutiny in multiple countries due to their structural similarity to gambling — several European jurisdictions have regulated or banned the mechanic. Genshin Impact, Honkai: Star Rail, Blue Archive, and Nikke exemplify the genre's production quality today. A common misconception is that gacha games are pay-to-win — most major gacha games are carefully balanced so that F2P players can complete all story content, with spending primarily affecting collection completion speed.

An action game subgenre focused on fast-paced, stylish combat against large groups of enemies, emphasising satisfying combos, aerial juggles, and increasingly complex attack strings that reward mastery. Unlike soulslikes where methodical patience is rewarded, hack-and-slash games reward aggression and style — standing still is punished, and the player is incentivised to maintain continuous offensive pressure across waves of enemies. The genre traces its lineage to arcade brawlers like Final Fight (1989) and Golden Axe, but crystallised as a distinct form with Devil May Cry (2001), which introduced the stylistic ranking system (SSS to D) that scores how creatively varied the player's attacks are. Devil May Cry 5, Bayonetta 1 & 2, Metal Gear Rising: Revengeance, and Stellar Blade are considered the genre's modern benchmarks. Dynasty Warriors represents a separate 'musou' branch of hack-and-slash where the appeal is clearing hundreds of enemies simultaneously for power fantasy fulfilment. God of War blends hack-and-slash combat with narrative depth and soulslike weight, creating a hybrid that expanded the genre's audience. A common criticism is that hack-and-slash games have high skill ceilings but thin narrative — they are pure systems games designed to be practiced and mastered rather than experienced once.

Video games developed by independent studios without major publisher funding, corporate ownership, or the backing of a large parent company, typically created by small teams ranging from one person to around 30 developers. The term 'indie' carries connotations of creative independence — without publisher approval requirements, indie developers can take design risks, explore unconventional themes, and avoid the commercial pressure to appeal to the broadest possible audience that shapes AAA development. The indie scene has produced genre-defining and culturally significant games: Minecraft (Markus Persson, solo developer), Undertale (Toby Fox, solo), Stardew Valley (ConcernedApe, solo), Hollow Knight (Team Cherry, 3 developers), Celeste, Hades, Disco Elysium, and Outer Wilds are all indie titles that achieved critical acclaim and commercial success beyond their development budgets. Digital distribution — primarily Steam — removed the gatekeeping barrier of physical retail, enabling indie developers to self-publish to global audiences with relatively low platform fees. The challenge for indie developers is discoverability: Steam releases approximately 15,000–20,000 titles per year, and organic discovery without a publisher's marketing budget is difficult. Indie publishing labels (Devolver Digital, Annapurna Interactive, Raw Fury) have emerged to provide marketing and distribution without creative control — a middle ground between pure independence and AAA publisher relationships.

Japanese Role-Playing Game — a subgenre of RPGs developed primarily in Japan, typically characterised by menu-driven or semi-real-time combat, anime-influenced art direction, linear or semi-linear story progression, party-based gameplay with multiple controllable characters, and elaborate musical scores. JRPGs became a global phenomenon through console releases on the NES and Super Famicom: the Final Fantasy and Dragon Quest series defined the template from the late 1980s onward, with Final Fantasy VII (1997) becoming the breakthrough title in Western markets. Key characteristics include heavy narrative investment — JRPGs routinely run 40–100 hours — and character development arcs that blend personal and world-saving storylines. Sub-genres within JRPGs include: Persona-style social sim RPGs, tactical JRPGs (Fire Emblem, Final Fantasy Tactics), action JRPGs (Tales of, Xenoblade Chronicles), and the emerging 'HD-2D' style (Octopath Traveler). Modern defining examples are Persona 5 Royal, Final Fantasy XVI, Like a Dragon: Infinite Wealth, and Metaphor: ReFantazio. The genre's primary criticism is pacing — mandatory random encounters, cutscene density, and filler dungeons can pad run-times. Remasters and 'remaster-adjacent' releases have given classic JRPGs new life on current hardware.

A game model in which the title is designed for ongoing, indefinite engagement rather than being a complete, self-contained experience. Live-service games are updated continuously with new seasonal content — new characters, maps, modes, cosmetics, story chapters, and balance patches — and monetised through recurring purchases such as battle passes or cosmetic item shops rather than one-time game sales. The model originated in PC gaming with MMORPGs and online shooters, but was industrialised for mass markets by Fortnite (Epic Games, 2017), which demonstrated that a free-to-play live service could generate billions in annual revenue through cosmetic purchases alone. Major live-service games include Fortnite, Apex Legends, Destiny 2, League of Legends, Path of Exile, and Genshin Impact. The model creates a fundamental tension: players want significant content updates, but live-service development is expensive and teams can struggle to maintain quality while shipping every six to twelve weeks. When a live service fails to attract or retain players, it faces a death spiral — falling population reduces matchmaking quality, reducing incentives to play, reducing population further. Many live-service games have been shut down, including Anthem, Babylon's Fall, and Hyenas.

A virtual container purchased with real money or earned through gameplay that opens to reveal a randomised selection of in-game rewards — cosmetics, characters, currency, gameplay items, or consumables — at variable rarity tiers, with rare items having low published probability rates. The mechanic is structurally analogous to physical collectible card packs and capsule toy machines (gashapon). Loot boxes achieved mainstream commercial success in FIFA's Ultimate Team mode (Electronic Arts, 2009), which used randomised player card packs to build a multi-billion-dollar annual revenue line, and in Overwatch (Blizzard, 2016), where cosmetic-only loot boxes generated significant controversy despite not affecting gameplay. The Netherlands and Belgium banned loot boxes in 2018, classifying them as gambling under existing consumer protection laws — triggering game publishers to remove the mechanic from those markets or shut down entirely (Valve removed CS:GO case sales in Belgium). The UK Gambling Commission's 2017 review found loot boxes did not technically meet the legal definition of gambling because the items had no external monetary value, a finding widely criticised as a regulatory gap. Following sustained public pressure, Overwatch 2 removed loot boxes in favour of direct purchase cosmetics, and EA reduced the prominence of Ultimate Team packs' random element. The industry trend post-2019 has moved toward battle passes (known odds, predictable content) and direct purchase cosmetics as alternatives that avoid loot box controversy.

A layer of persistent progression that exists above the run-level systems in a roguelite — upgrades, unlocks, and permanent bonuses that carry over between attempts and accumulate over a player's entire history with the game, rather than resetting on death. Meta-progression fundamentally changes the roguelite experience compared to pure roguelikes: no run is ever fully wasted, because every attempt earns something toward the wider progression arc. In Dead Cells, meta-progression unlocks new starting gear and ability cells that increase power in future runs. In Hades, players upgrade the Infernal Arms, unlock new Boons, and progress the story through the hub regardless of how far they reach in any individual escape attempt. In Slay the Spire, meta-progression unlocks new card options and events that add strategic variety. The design challenge for meta-progression is calibration: too weak and it feels meaningless; too strong and it trivialises the run-level challenge by making the player overpowered. Many roguelites deliberately slow meta-progression to keep individual runs tense for longer. 'Catch-up' meta-progression — where struggling players gain accelerated upgrades — is a common accessibility design choice in mobile roguelites.

A genre of 2D action-adventure games built around interconnected maps where progression is gated by abilities your character has not yet acquired. You explore freely until you hit a barrier — a high ledge, a locked door, a water section — that requires a specific power-up or ability to pass. Once gained, that ability unlocks not just the new area but also rewards hidden earlier in the game, encouraging backtracking across a richly layered world. The name is a portmanteau of Metroid (Nintendo, 1986) and Castlevania: Symphony of the Night (Konami, 1997), the two series that codified the formula. The genre's structure creates a satisfying sense of mounting mastery: the same world that was intimidating at the start feels familiar and navigable once you're fully powered up. Modern genre-defining examples include Hollow Knight, Ori and the Blind Forest, Blasphemous, Axiom Verge, and Dread Templar. Many Metroidvanias are indie titles because the interconnected map design suits smaller development teams. A common misconception is that any 2D game with exploration qualifies — true Metroidvanias require hard ability gating and intentional backtracking design, not just open levels.

A small real-money purchase made within a game, typically for individual cosmetic items, in-game currency bundles, consumable boosts, or content unlocks. Despite the 'micro' prefix, individual transactions frequently cost $5–$25, and spending can accumulate into hundreds or thousands of dollars for engaged players. Microtransactions are the primary revenue mechanism for free-to-play games and are also common in premium-priced titles. The practice emerged in PC browser games and Asian MMOs in the early 2000s before migrating to console games with the Xbox 360 and PlayStation 3 generation's introduction of digital storefronts. Three distinct categories define most microtransaction ecosystems: cosmetic-only (character skins, emotes, sprays — League of Legends, Fortnite) which are broadly accepted because they don't affect gameplay; currency-to-randomised-rewards (loot boxes, gacha) which have faced regulatory scrutiny for gambling parallels; and pay-to-win or pay-to-progress-faster which are criticised for compromising game integrity. The most commercially successful microtransaction-driven game is Genshin Impact, which has generated over $4 billion in mobile revenue alone since 2020. Regulators in Belgium, the Netherlands, and several other European jurisdictions have acted against randomised microtransactions; the UK Gambling Commission concluded in 2017 that loot boxes are not technically gambling under existing law but flagged consumer protection concerns.

Massively Multiplayer Online Role-Playing Game — a genre in which thousands of players simultaneously inhabit a shared persistent online world, developing characters through quests and combat, forming social guilds, and engaging in both cooperative (PvE) and competitive (PvP) content. The persistent world continues to exist and change whether any given player is logged in or not. The genre traces its origins to text-based MUDs (Multi-User Dungeons) in the late 1970s, with EverQuest (1999) establishing the modern 3D template and World of Warcraft (2004) achieving mainstream adoption with 12 million subscribers at its peak. WoW's design — quest-driven levelling, instanced dungeons, public raid bosses, auction houses, and gear-score progression — became the template almost every subsequent MMORPG followed. Final Fantasy XIV, rebuilt after a disastrous 2010 launch into one of the genre's most critically acclaimed examples, and Guild Wars 2, which removed monthly subscriptions, represent the genre's modern creative successes. MMORPGs are distinguished by their social depth: raiding guilds, player economies, and server communities create relationships that persist for years. The genre's primary challenge is content saturation — maintaining a 'live world' requires enormous ongoing development resources, and most players exhaust available content faster than studios can produce it.

Multiplayer Online Battle Arena — a genre in which two teams of five players each control individual hero characters and compete to destroy the opposing team's base structure (the Nexus in League of Legends, the Ancient in Dota 2). MOBAs are characterised by their top-down camera perspective, three-lane map structure with jungle areas between lanes, last-hitting neutral and enemy creeps to earn gold, a deep itemisation system, and a large roster of asymmetric hero characters each with unique ability kits. The genre traces its origin to Defense of the Ancients (DotA), a WarCraft III custom map created by community modders in the early 2000s that became so popular Valve hired the lead developer to build Dota 2 (2013). League of Legends (Riot Games, 2009) became the world's most-played PC game by simplifying Dota's complexity for a broader audience. Mobile MOBAs — Mobile Legends: Bang Bang, Honor of Kings, and Wild Rift — have eclipsed their PC counterparts in player count across Southeast Asia and China. MOBAs have the steepest learning curves in gaming: understanding a 150+ hero roster, itemisation, vision control, macro rotation, and team composition theory requires hundreds of hours of study. Despite — or because of — this complexity, League of Legends and Dota 2 remain the cornerstones of competitive esports globally.

The practice of creating community-made modifications to a game's files — altering gameplay systems, adding new content, fixing developer-overlooked bugs, upgrading visual fidelity, or in extreme cases creating entirely new games built on existing engines. PC gaming has the richest modding ecosystem because open platforms allow file access; consoles have historically restricted modding, though select games like Skyrim and Fallout 4 support mods on PlayStation and Xbox via official mod portals. The modding ecosystem is distributed through Nexus Mods (PC-focused, over 500 million downloads), the Steam Workshop (directly integrated into Steam's game pages), and CurseForge (Minecraft, World of Warcraft). Some of the most commercially influential games in history began as mods: Counter-Strike started as a Half-Life mod; Dota began as a WarCraft III custom map; Teamfortress began as a Quake mod; and DayZ (a zombie survival mod for ARMA 2) spawned the entire survival game genre. Bethesda's RPGs — Morrowind, Oblivion, Skyrim, Fallout 4 — have particularly active modding communities that keep decade-old games contemporary through visual overhauls, new questlines, gameplay overhauls, and bug fixes that sometimes exceed the quality of official patches. Modding represents gaming's creative underclass: the players who move from consuming games to shaping them.

A game design philosophy where players can explore a large, persistent environment with minimal scripted funnelling between areas — visiting locations, pursuing objectives, and interacting with systems in any order they choose. Open-world games typically feature a main questline that can be deferred in favour of side quests, dynamic events, collectibles, crafting, exploration challenges, and emergent player-created scenarios. Grand Theft Auto III (2001) demonstrated that open-world design could work at commercial scale, sparking an industry-wide shift; Bethesda's Elder Scrolls and Fallout series refined the formula for RPG audiences. The genre reached a design peak with The Legend of Zelda: Breath of the Wild (2017), which redesigned all open-world conventions around player physics-based experimentation. Red Dead Redemption 2, Elden Ring, and Ghost of Tsushima are widely regarded as technical and artistic benchmarks of the form. A recurring tension in open-world design is content density vs. meaningful exploration: open worlds stuffed with icons and collectibles (Ubisoft formula) feel like checklists rather than living environments. The best open worlds reward players who wander off the marked path and discover content through curiosity rather than map icons.

Official documentation released by game developers listing all changes included in a specific game update — covering bug fixes, balance adjustments, new content additions and removals, performance improvements, and changes to systems and mechanics. Patch notes are the primary channel through which developers communicate mechanical changes to their playerbase, and for competitive games they are critical reading: a balance change nerfing a dominant character or weapon can completely shift which strategies are viable, and players who read patch notes before their next session have meaningful competitive preparation over those who don't. Games with the most community-engaged patch note cultures include League of Legends and Valorant (Riot publishes notes every two weeks with designer commentary), Path of Exile (patch notes for major expansions run to tens of thousands of words), and Hearthstone (balance patches trigger immediate tier-list reassessments). Modern patch note communication has expanded beyond text: many games include developer blogs, video breakdowns from community managers, and official 'patch preview' streams where designers discuss intent alongside the mechanical changes. A patch note's quality reflects developer transparency — notes that explain the reasoning behind changes ('we're nerfing X because win rate in Diamond+ was 58% for 3 weeks') are more valuable than bare changelogs because they communicate design intent and help players anticipate future directions.

A pejorative term for a game monetisation model in which spending real money provides tangible, meaningful competitive advantages over non-paying players — stronger weapons with higher base stats, exclusive abilities not obtainable through play, stamina restoration that allows faster progression, or direct purchase of higher-level equipment. Abbreviated P2W. Pay-to-win is widely considered antithetical to fair competitive design because it allows financial resources to substitute for player skill and time investment. The line between acceptable and pay-to-win monetisation is disputed: content that accelerates progression (experience boosts, resource doublers) is considered light P2W by critics but acceptable quality-of-life by publishers. Most major competitive titles — League of Legends, Valorant, Fortnite — are explicitly cosmetic-only in their monetisation, having learned that P2W accusations destroy competitive player trust. Mobile gaming has the most aggressive P2W implementations: gacha games with combat-relevant characters available only through draws, strategy games with premium buildings, and RPGs with paid equipment tiers are all endemic on app stores. Diablo Immortal (2022) became a flashpoint for pay-to-win controversy when analysis revealed the endgame upgrade system required tens of thousands of dollars to max out, despite being published by Blizzard — a company with a history of cosmetic-only monetisation in its other franchises.

Gaming on personal computers — desktops, laptops, and handheld PCs — running Windows, macOS, or Linux. PC gaming offers capabilities that console hardware cannot match: upgradeable components allow players to target 4K at 120fps or above; mice and keyboards provide input precision critical for strategy games and competitive shooters; and open platform software distribution means unlimited game libraries with no platform exclusivity in most cases. The primary digital storefronts are Steam (Valve), which dominates the market, Epic Games Store (notable for free weekly game giveaways), GOG (DRM-free focus), and EA App, Ubisoft Connect, and Battle.net for publisher exclusives. PC is the dominant platform for strategy games (Total War, Civilization), MOBAs (League of Legends, Dota 2), competitive FPS (Counter-Strike 2, Valorant), and MMORPGs. Modding culture — community-created modifications that add content, fix bugs, or transform games entirely — is unique to PC and extends the lifespan of titles like Skyrim and Minecraft for decades. The trade-off versus console is higher upfront cost (a capable gaming PC costs $800–$1500+ versus $500 for a console) and the complexity of maintaining drivers, settings, and troubleshooting. The Steam Deck (2022) extended PC gaming to a handheld form factor, running the full Steam library in portable play.

A game mechanic in which the death of the player's character is permanent — there is no respawning at a checkpoint, no save reloading, and no second chance. When the character dies, the run (or the entire save file, in its strictest implementation) ends, and the player must start over from the beginning. Permadeath is the defining feature of the roguelike genre, where it serves a specific design purpose: every resource decision — whether to use a healing item now or save it for later, whether to engage or retreat — carries real weight because the consequences are irreversible. This creates a quality of tension and focus impossible to replicate when death has no cost. In some games, permadeath exists as an optional mode: Diablo IV Hardcore, Minecraft Hardcore, XCOM's Ironman mode, and The Binding of Isaac all offer permanent death as a challenge layer on top of a game that normally allows retries. Some narrative games use permadeath for named companions (Fire Emblem's classic mode) where the emotional attachment to characters makes their loss genuinely impactful rather than mechanically inconvenient. A common beginner mistake is assuming permadeath makes games 'unfair' — in well-designed permadeath games, deaths are almost always the result of a learnable mistake, not random bad luck.

A technique where game content — levels, maps, items, quests, enemies, or entire worlds — is created algorithmically at runtime using defined rules and randomised seeds, rather than being hand-crafted by a designer. Procedural generation enables theoretically infinite content variety from a finite set of authored rules, making it a cornerstone of the roguelike and sandbox genres. The technique has been used in games since the 1980s (Rogue, Elite), but has been elevated by modern computational power: No Man's Sky (2016) uses procedural generation to create 18 quintillion unique planets with distinct ecosystems, weather, and terrain. Other major applications include Minecraft's infinite biome generation, Diablo's dungeon layouts, and Path of Exile's modular item affix system. The core trade-off of procedural generation is depth vs. coherence: algorithmically generated content can produce extraordinary variety but sometimes lacks the intentional design beats that make hand-crafted levels feel carefully authored. The best procedurally generated games (Dwarf Fortress, Hades) solve this by using procedural generation for spatial layouts while keeping authored content — story beats, unique items, character writing — hand-made.

Player versus Player — any game mode in which the primary challenge and opposition comes from other human players rather than AI-controlled enemies or environmental hazards. PvP spans an enormous range of formats: ranked ladders in MOBAs and fighting games where individual skill determines outcomes; team-based objective modes in FPS games (capture the flag, bomb defusal, payload); battle royale free-for-alls; world PvP in MMORPGs where any player in designated zones can be attacked; and asymmetric PvP (Dead by Daylight) where players occupy different roles with fundamentally different mechanics. The appeal of PvP is the unpredictability and social stakes that AI cannot replicate — human opponents adapt, counter-strategise, and respond to mind games in ways that make victories feel more meaningful than defeating scripted enemies. Designing balanced PvP requires continuous attention to the 'meta' — the currently dominant strategies and character selections — to prevent a single tactic from rendering all others non-viable. Ranked PvP creates long-term engagement through visible skill progression, while casual unranked modes keep the game accessible to players who want competition without the anxiety of rank loss.

A competitive matchmaking mode in multiplayer games where wins, losses, and individual performance affect a visible skill rating or tier rank, designed to match players against opponents of similar ability over time. Ranked systems use various models: Elo (named after Arpad Elo, originally designed for chess) calculates a single numerical skill rating updated after each match; MMR (Matchmaking Rating) is a hidden internal version of Elo used by many games behind visible tier displays; and league-based tiers — Iron, Bronze, Silver, Gold, Platinum, Emerald, Diamond, Master, Grandmaster, Challenger in League of Legends — translate internal MMR into visible prestige milestones. Ranked modes serve several design purposes: they separate players who want competitive intensity from those who prefer casual play; they provide a long-term progression goal (climbing the ladder) that extends game engagement; and they create a meritocratic arena for skilled players who find casual matches too easy. Ranked modes are the foundation of esports talent pipelines — professional players are typically drawn from the top ranks of open ranked queues. Common ranked frustrations include 'elo hell' (the belief that a player is stuck in a rank due to teammates rather than personal skill), rank decay for inactivity, and placement match variance at the start of each season resetting accumulated progress.

A real-time rendering technique that simulates the physical behaviour of light rays — accurately calculating reflections, refractions, ambient occlusion (soft shadowing in crevices), global illumination (light bouncing off surfaces), and caustics (light focused through transparent materials) — to produce photorealistic lighting that rasterisation-based rendering cannot replicate without baked approximations. Traditional rasterisation renders scenes by projecting geometry onto a flat plane and applying pre-calculated lighting — fast, but reliant on hacks for reflections (screen-space reflections break at screen edges) and soft shadows. Ray tracing casts simulated rays from the camera through each pixel, testing intersections with scene geometry and light sources, to compute true optical behaviour at the cost of significant GPU computation. NVIDIA introduced real-time ray tracing hardware acceleration in its Turing RTX series (2018); AMD followed with RDNA2 (2020), which also powers PlayStation 5 and Xbox Series X. Visually, ray tracing's most noticeable impact is on reflective surfaces (wet streets, windows, polished metal) and interior lighting (realistic bounce light in enclosed spaces). Most current-generation console games offer a 'Quality mode' (ray tracing enabled, 30fps target) vs 'Performance mode' (ray tracing disabled or reduced, 60fps target) split. DLSS, FSR, and XeSS upscaling are typically used to recover performance lost to ray tracing on PC.

A subgenre of role-playing games defined by three core pillars: procedurally generated levels that create a unique map layout every run, permadeath meaning your character's death ends the run permanently with no save reloading, and turn-based or real-time tactical gameplay that rewards careful decision-making. The genre takes its name from Rogue, a 1980 dungeon-crawling game by Michael Toy and Glenn Wichman developed on UNIX systems. What makes roguelikes so replayable is that no two runs are identical — the dungeon layouts, item placements, enemy types, and random events all change every time you start fresh, ensuring hundreds of hours of distinct play. Pure roguelikes adhere strictly to all original conventions (permadeath, turn-based, grid movement, high complexity) — examples include NetHack, Dungeon Crawl Stone Soup, and Caves of Qud. The more casual 'roguelite' branch borrows the aesthetic while softening the rules with persistent unlocks. A common misconception is that Hades is a roguelike — technically it is a roguelite because retained currency and hub upgrades survive each death. The best roguelikes reward mastery: a skilled player learns item synergies and threat hierarchies well enough to achieve consistent victories despite the procedural randomness.

Hades is one of the best roguelites ever made — it adds meta-progression on top of the roguelike formula, making each death feel like progress.

A genre that borrows the core pillars of roguelikes — procedurally generated levels and permadeath — but layers in persistent meta-progression that carries over between runs, softening the harshness of starting from scratch. When you die in a roguelite, you retain currency, unlocks, or passive upgrades that make future attempts slightly more powerful or give you more starting options. This persistent layer fundamentally changes the player psychology: every failed run contributes something, turning frustration into motivation. Hades, Dead Cells, Risk of Rain 2, Slay the Spire, and Vampire Survivors are defining roguelites. The term emerged in the early 2010s as game designers adapted the roguelike formula for wider audiences who found pure permadeath discouraging. The distinction matters because roguelites can be 'beaten' by accumulating enough meta-progress, while pure roguelikes demand raw skill from run one. Roguelites often also use real-time action combat rather than the turn-based movement found in traditional roguelikes, making them feel faster and more action-oriented. The genre is now one of the most popular in indie gaming, with new roguelites releasing every month across all platforms.

A network synchronisation architecture used in fighting games — and increasingly other competitive genres — in which each player's game client locally predicts (simulates) the opponent's current inputs rather than waiting for those inputs to be confirmed over the network, then immediately 'rolls back' and recomputes game state if the prediction proves incorrect when the actual input arrives. The alternative, delay-based netcode, inserts an artificial input buffer of several frames on both players to allow network packets to arrive before processing, creating a lag-like sluggishness even on fast connections. Rollback produces online play that feels nearly identical to offline play even at 80–120ms latency, because the client never 'waits' — incorrect predictions correct silently, and at typical prediction error rates the corrections are nearly invisible. The GGPO library (created by Tony Cannon in 2007) provided the first accessible rollback implementation for fighting games, and games using it — Street Fighter III: 3rd Strike Online, UMvC3, Skullgirls — demonstrated the quality gap versus delay-based alternatives. The modern rollback expectation for new fighting games was set by Guilty Gear Strive (2021), Street Fighter 6 (2023), and Tekken 8 (2024). Rollback adoption is not universal: some older fighting games still run on delay-based netcode because rollback implementation requires significant engine access, and retrofitting it to legacy titles is costly. Dead or Alive 6, while technically advanced in gameplay, still uses delay-based netcode — a commonly cited reason competitive players avoid it online.

A game genre that prioritises player freedom and emergent creativity over predefined objectives, providing tools, materials, and a malleable world for players to interact with according to their own goals. In a sandbox game, the designer's role is to build interesting systems and give players the means to engage with them; what the player actually does with those systems is left entirely open. Minecraft (2011) is the definitive sandbox game — its block-based world can be shaped into anything from functional computers to faithful recreations of real-world architecture, with no in-game reward for doing so beyond the intrinsic satisfaction of creation and exploration. Other genre staples include Terraria (2D sandbox with Metroidvania-style progression), Valheim (survival-craft sandbox in Norse mythology), and Garry's Mod (physics sandbox built on Source Engine). The term 'sandbox' is also used loosely for open-world games with high player agency (Grand Theft Auto V), though these typically have structured missions and objectives that pure sandbox games lack. Sandbox games generate exceptional long-term engagement because player-created content continuously refreshes the experience — a Minecraft world at 1000 hours is entirely different from the same world at 10 hours.

Skill-Based Matchmaking — a system that matches multiplayer players against opponents of statistically similar skill level, using performance metrics such as kill-death ratio, win rate, accuracy, or internal MMR (Matchmaking Rating) calculated from match history. SBMM is deployed in most major competitive multiplayer titles as a fairness and retention mechanism: without it, new players are placed against experienced ones and churn rapidly; with it, players face challenges appropriate to their level and have a more balanced experience. The system became a point of significant player controversy in the Call of Duty franchise following Warzone and Modern Warfare's strict SBMM implementation. Critics argue that strict SBMM eliminates the natural variance of casual lobbies that previously let skilled players enjoy 'easy' lobbies mixed with hard ones, creating a 'sweaty' experience where every match feels equally competitive with no relief. Supporters note that without SBMM, player skill disparity creates unplayable experiences for below-average players who make up the majority of any game's playerbase. The debate revealed a fundamental tension in multiplayer game design: SBMM optimises for fair matches (better for new and average players) while degrading the experience for above-average players who enjoyed the variety of mixed-skill lobbies. Some games have explored 'soft SBMM' — weighting skill alongside other factors like party size, connection quality, and map variety to prevent any single dimension from dominating matchmaking decisions.

A bundle purchase providing access to all downloadable content (DLC) released for a game within a defined period — typically one to three years following the base game's launch — at a discount versus purchasing each piece of DLC individually at release. Season passes are sold before the DLC is available, requiring the buyer to trust that future content will justify the upfront cost. The model was prominent in the mid-2010s as publishers structured their DLC release cadence around a season pass bundle: players who bought in early received guaranteed access to all announced expansions, while individual DLC buyers paid more per unit. The Witcher 3: Complete Edition, which bundled two major expansions (Hearts of Stone and Blood and Wine) representing some of the best content in gaming, is often cited as a season pass that definitively delivered its value. Conversely, Battlefield 4's Premium Pass split the player base by locking large portions of the map pool behind it, fragmenting matchmaking and frustrating players who didn't purchase it. Season passes have declined in popularity as live-service battle passes — which are recurrent, lower-cost, and deliver content within a predictable seasonal window — replaced them as the dominant forward-monetisation structure. Some publishers still use the season pass model for singleplayer-focused games with planned expansion DLC, where the content structure maps better to a bundle than to ongoing seasonal releases.

A subgenre of action RPGs defined by FromSoftware's Dark Souls trilogy and its design philosophy: challenging, methodical melee combat built on stamina management and pattern recognition; death as a teaching tool rather than a punishment (you lose carried currency but respawn at a checkpoint); minimal hand-holding with lore delivered through item descriptions and environmental detail rather than exposition; and interconnected world design that reveals surprising shortcuts as you explore. FromSoftware director Hidetaka Miyazaki established the template with Demon's Souls (2009) and refined it through Dark Souls (2011), Bloodborne (2015), and Elden Ring (2022). The genre's appeal lies in the satisfaction of conquering bosses that seemed impossible after dozens of attempts — every death contains information. Soulslikes beyond FromSoftware include Lies of P, Nioh 2, The Surge 2, and Lords of the Fallen (2023). A key distinction: soulslikes are hard but fair — deaths result from the player failing to read patterns, not from random unfairness. Elden Ring broadened the template by adding open-world exploration, allowing players to tackle the game's challenges in flexible order and making it the most accessible entry point for newcomers to the genre.

A playthrough of a video game with the goal of completing it as quickly as possible, typically using a combination of optimised movement strategies, sequence breaks (reaching later game areas before intended), and deliberate exploitation of programming bugs and glitches that manipulate game state in unintended ways. Speedrunning has a substantial community infrastructure: Speedrun.com serves as the primary leaderboard repository across thousands of game categories; GDQ (Games Done Quick) charity marathons broadcast curated speedruns to hundreds of thousands of live viewers; and individual runners build Twitch and YouTube audiences around routing research, world record attempts, and learning guides. The major run categories are: Any% (complete the game by any means, using any discovered glitch or skip, resulting in the fastest possible time regardless of game content missed); 100% (complete all objectives, collectibles, and requirements the game tracks); and Glitchless (complete the game without exploiting programming bugs, testing pure movement and routing optimisation). Games with large speedrunning communities include The Legend of Zelda: Ocarina of Time (where a 'wrong warp' glitch allows a sub-6-minute any% from a 30-hour game), Dark Souls, Super Mario 64, and Hades (where the community runs all heat levels and all weapon types). The social and analytical dimensions of speedrunning — routing theory, glitch discovery, record competition — make it a form of competitive play distinct from and parallel to conventional multiplayer.

A handheld gaming PC manufactured by Valve and released in February 2022, running SteamOS — a Linux-based operating system built on Arch Linux with a custom game mode UI called 'Gaming Mode' that presents the Steam library in a console-style interface. The Steam Deck is powered by a custom AMD APU (CPU + GPU on one chip) providing enough performance to run the vast majority of the Steam library at 60fps or above in medium to low settings, and it supports the full range of PC peripherals via its USB-C port for use as a desktop. Valve rates games in three tiers on the Steam Deck: Verified (fully compatible), Playable (works with minor caveats), and Unsupported (doesn't launch or has major issues). Many Windows-only games run via Proton, Valve's compatibility layer, which translates Windows DirectX calls to Vulkan. The Steam Deck OLED, released in November 2023, significantly improved battery life and upgraded to a vibrant OLED display. The device created a new category of portable PC gaming that competitors — Asus ROG Ally, Lenovo Legion Go, and MSI Claw — have since entered with Windows-based alternatives. For players with large Steam libraries, the Steam Deck offers a way to play existing owned games portably without repurchasing a separate portable library.

A cross-promotional reward system in which game publishers partner with Twitch to distribute in-game items — cosmetics, beta access keys, loot boxes, premium currency, or exclusive content — to viewers who watch designated streams for a qualifying duration. Players must link their Twitch account to the relevant game account, watch qualifying streams for a set threshold (typically 30 minutes to 4 hours), and then claim the reward through a Twitch notifications panel. Game publishers use Drops campaigns to incentivise viewership during high-visibility windows: game launches, esports tournament broadcasts, content creator partnerships, and limited-time events. Drops serve dual purposes: they increase stream viewership metrics (important for ranking and recommendation visibility on Twitch) and they drive player acquisition and re-engagement by attaching tangible rewards to the watching experience. Twitch Drops campaigns are most prevalent in live-service games with dedicated esport viewership — Valorant (Champions Tour drops), Path of Exile (league launch viewing campaigns), Diablo IV, and Destiny 2 all run regular Drops periods. A common player frustration is that Drop campaigns require concurrent viewing rather than VOD viewing — you must watch the live stream in real time. Multiple simultaneous campaigns from different games can create 'Drops fatigue' where a player keeps multiple browser tabs open to accumulate rewards across titles they don't actively play.
