Enable an AI agent to recognise a massively multiplayer online role-playing game, assess the condition of its persistent worlds and participation systems, and determine which actions are available and permitted.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Enable an AI agent to recognise a massively multiplayer online role-playing game, assess the condition of its persistent worlds and participation systems, and determine which actions are available and permitted.
A networked role-playing video game in which a large concurrent player population inhabits a persistent shared virtual world, each player embodied as a character whose abilities, inventory and social standing accumulate through play and remain in the world between sessions.
It can be Identify the relevant edition, realm and ruleset before interpreting character or service state.; Assess whether an authorised player can enter a world or join a specified activity using current eligibility and access evidence.; Compare progression paths and explain their prerequisites, costs, reset exposure and reversibility.; Evaluate whether proposed grouping, trading or character-transfer actions are supported and permitted.; Track service changes that affect persistent characters, social groups or virtual assets.; Perform supported interactions through authorised interfaces when both the user and applicable game rules permit them..
Distinguishing features
Participants develop persistent player characters with consequential roles, abilities or attributes across multiple sessions; a shared online lobby alone does not establish role-playing persistence.
The game organises participation around an enduring shared world or world population, rather than only isolated matches whose social and gameplay state ends with each match.
Its multiplayer architecture supports a population beyond a single fixed cooperative party, although evidence must establish how that population is divided among realms, zones and instances.
Character progression and interactions with other players are central playable systems; a social virtual world with optional role-play does not qualify on that feature alone.
Separate instances can coexist with MMORPG identity when they connect to persistent characters and a broader shared-world population; simultaneous visibility of every participant is not required.
Scope
+ Game identity, editions and boundaries between official services, realms, shards and regional versions
+ Persistent characters, role differentiation, progression and consequences of character choices
+ Shared-world population, social organisation and cooperative or competitive play
+ Virtual goods, currencies, trading and progression-related monetisation
+ Access conditions, player permissions, moderation and service availability
+ Updates, seasonal resets, migrations and preservation or loss of persistent player state
- Player identities, personal circumstances and account credentials
- Individual computers, consoles, network connections and hosting infrastructure
- The developer or publisher as an organisation
- Payment processing, banking and external marketplaces as independent services
- Standalone lore, fictional characters and other works within the same franchise
- Separate private-server services or derivative games whose relationship requires its own model
Characteristics
- Service and version identity
- Named game, edition, ruleset, region, operator and observation date Prevents an agent from applying the population, rules or availability of one service variant to another.
- Character persistence regime
- Retained character attributes and inventory; reset, death, deletion and migration conditions Shows which player investments survive sessions and which actions may destroy or alter them.
- Population partitioning
- Realm, shard, zone, channel and instance arrangement; cross-partition interaction rules Determines whether particular players can meet, trade or participate together.
- Concurrent population
- Concurrent players, with measured boundary, timestamp, sampling method and distinction between observed count and capacity Supports assessment of multiplayer scale and availability of population-dependent activities.
- Progression structure
- Level, skill, equipment, reputation, narrative or mixed progression; caps and prerequisites Explains character eligibility and which activities can change capabilities.
- Activity participation requirements
- Party size, role composition, character prerequisites, schedule, region and matchmaking conditions by activity Allows an agent to assess whether an intended activity is currently feasible.
- Economic transfer rules
- Tradeable, character-bound, account-bound or otherwise restricted, by asset type and transfer channel Prevents assumptions that possession implies permission or ability to transfer a virtual asset.
- Operational lifecycle
- Announced, testing, live, restricted, maintenance, closing or closed, qualified by service boundary and evidence date Determines whether participation, migration or preservation actions remain available.
- Automation permission
- Permitted, conditional, prohibited or unresolved, by action, interface and applicable policy version Separates technically possible agent actions from actions the game operator allows.

Drafted structure
Bundle to layer to finding to question, as the second pass will find it: 6 bundles · 11 layers · 18 findings · 28 questions.
World identity and population The boundaries that make a service a particular MMORPG and organise its shared population.
Recognition and participation decisions require distinguishing the game from its editions, isolated instances and separately operated worlds.
Game and service boundaries
Identity relationships among the title, editions, rulesets and operated services.
MMORPG identity evidence
Record evidence for persistent role-playing characters, enduring multiplayer context and population scope without relying solely on a marketing label.
- Which persistent character systems and shared-world interactions establish that this service functions as an MMORPG? definition
- Which editions, regional services or rulesets belong to this game identity, and which require separate treatment? boundary
Population topology
How players are partitioned and which forms of interaction cross those partitions.
Shared-world reach
Record realm, channel, zone and instance boundaries alongside evidence of population and interaction across them.
- Across which realms, regions or instances can players meet, communicate, group and trade? boundary
- What concurrent population is observed at each relevant boundary, when was it measured, and does the evidence report actual players or configured capacity? measurement
Characters and progression Persistent player roles, capability growth and the consequences of character development.
An agent needs to understand what a character can become, what it can currently attempt and which investments may be lost.
Character continuity
The identity, ownership scope and persistence of playable character state.
Persistent character state
Record which capabilities, possessions and achievements attach to a character, account, realm or season and how their continuity can end.
- Which abilities, inventory, quest outcomes and achievements persist, and at what character, account or world scope? definition
- What happens to that state after death, character deletion, inactivity, seasonal reset or realm transfer? action
Roles and advancement
How character builds, progression systems and prerequisites determine playable options.
Capability and eligibility paths
Record consequential build choices, advancement requirements and options for revising character development.
- Which levels, skills, equipment, reputations or narrative milestones determine access to a specified activity? measurement
- Which role or build choices can be changed, and what costs, cooldowns or permanent consequences apply? action
Multiplayer activities and social order The activities and player organisations that make the persistent population operationally meaningful.
A character may satisfy formal requirements while lacking the group, authority or available participants needed to act.
Cooperation and competition
Participation conditions and consequences for shared activities.
Activity feasibility
Record the composition, scheduling, matchmaking and conflict rules of activities relevant to the intended action.
- What group size, role composition, unlocks, time windows and available population does this activity require? measurement

Persistent player organisations
Guilds, clans, alliances and other durable forms of player coordination.
Membership and shared authority
Record membership conditions and permissions over collective resources, events and territorial interests where supported.
- Which persistent player organisations exist, and what rights or obligations follow from membership and rank? definition
- Who may recruit, remove members, spend shared assets or commit the organisation to an activity, and can those actions be reversed? action
Virtual economy and access The creation, circulation and consumption of virtual value and the conditions for accessing gameplay.
Progression, trade and participation decisions depend on asset restrictions, resource availability and entitlement requirements.
Assets and exchange
Virtual currencies, items and the supported means of acquiring, consuming and transferring them.
Resource flows and transferability
Record relevant resource sources and sinks, asset binding and exchange conditions without assuming all goods have a market price.
- How are the relevant currencies and items created, earned, consumed or removed, and where are their balances held? definition
- Which assets can be transferred through which channels, with what binding rules, fees, limits and operator restrictions? action
Entitlements and monetisation
Purchase, subscription and other entitlement conditions that affect participation or character development.
Playable access and paid effects
Record which entitlements unlock content or capabilities and what changes when those entitlements expire.
- Which worlds, activities, character options and trading functions require a purchase, subscription or other entitlement? boundary
- What gameplay effects do paid offerings have, and what happens to access and persistent assets when an entitlement lapses? action
Operation, rules and world change The live service conditions and authorities governing participation and persistent state.
An agent must connect intended actions to current service availability, applicable rules and possible changes to accumulated player state.
Service continuity and change
Availability, updates and lifecycle events affecting worlds and characters.
Persistent state under service change
Record current operational status and announced changes affecting character continuity, economic state and player communities.
- Which service boundaries are currently playable, restricted or unavailable, and what dated evidence supports that status? provenance

Reported by the breadth pass; each item needs checking against its source before it becomes normative.
- Wikidata - Q862614 - Item for the genre, not for any single title.
- Steam tag - MMORPG - Storefront genre tag on individual products; not a controlled vocabulary with a numeric code.
- Common English initialism - MMORPG - Also shortened in speech and marketing to MMO, which is strictly the superclass.
- Which of these identifiers and schemes hold for the sense of massively multiplayer online role-playing game this model covers, and on what evidence? provenance
Standards and regulation
Reported by the breadth pass; each item needs checking against its source before it becomes normative.
- ESRB (Entertainment Software Rating Board, United States) age ratings applied to individual titles, not to the genre as a class.
- PEGI (Pan-European Game Information) age and content descriptors on individual titles.
- CERO (Computer Entertainment Rating Organization, Japan) ratings on individual titles.
- GRAC (Game Rating and Administration Committee, Republic of Korea) rating and online-game oversight; historically coupled with the now-repealed juvenile shutdown / 'Cinderella' night curfew (2011-2021).
- National Press and Publication Administration (China) licensing of online games, plus statutory play-time and spending limits for minors.
- GDPR (EU) and COPPA (United States, FTC) for account, chat and behavioural data when children or EU residents are in the player base.
- Loot-box and gacha rules treated as gambling in some jurisdictions (notably the Belgian Gaming Commission; also scrutiny by the Netherlands KSA and several Asian regulators) - applied to monetization inside titles, not to MMORPGs as such.
- Which of these standards and regulation hold for the sense of massively multiplayer online role-playing game this model covers, and on what evidence? provenance
Real-world use
Reported by the breadth pass; each item needs checking against its source before it becomes normative.
- Leisure play as a long-horizon hobby: levelling, raiding, crafting and guild social life, typically on a home PC or phone.
- Persistent social 'third place' (guilds, role-play communities, in-game weddings and memorials).
- Real-money economies: gold farming, power-levelling services, and official or grey-market item cash shops.
- Spectator and streaming content (raid races, world-firsts, EVE Online political coverage).
- Research site for virtual-world economics, social networks and addiction studies.
- Internet-cafe / PC-bang session play, especially in Korea and parts of Southeast Asia.

Typical measurements
Reported by the breadth pass; each item needs checking against its source before it becomes normative.
- Concurrent users (CCU) on a live title - about 1,000-300,000 for a healthy mid-to-large title; historical peaks for a few flagships in the low millions of subscribers, not CCU - players
- Round-trip latency to the game shard - 20-150 playable; above ~200-300 combat feels degraded - ms
- Simulation tick / net update rate - typically 8-30 (much lower than competitive FPS) - Hz
- Hours of play to first level cap (theme-park titles) - about 20-150 depending on era, boosters and design - h
- Retail subscription (boxed Western model) - about 10-15 - USD per month
- Players assigned per shard/realm (sharded titles) - roughly 2,000-15,000 advertised cap; single-shard sandboxes can hold far more in one universe - players

Failure modes and hazards
Reported by the breadth pass; each item needs checking against its source before it becomes normative.
- Shard crash, rollback, or prolonged login queue that strands a shared world.
- Duplication bugs, bots and speed hacks that destroy the in-world economy.
- Inflation and real-money trade that unbalance intended progression.
- Account takeover (credential stuffing, session theft) and item recovery disputes.
- Predatory monetization: gacha, time-gated cash shops, pay-to-win conversion.
- Problematic play / gaming disorder (ICD-11 6C51) and sleep/work displacement.
- Chat and voice social harms: harassment, scams, and grooming in a persistent social graph.
- Studio shutdown or merged-server sunset that erases player-created value with no portability.
- DDoS against login or realm hardware as a play-disruption and extortion vector.
- Which of these failure modes and hazards hold for the sense of massively multiplayer online role-playing game this model covers, and on what evidence? provenance
Regional variation
Reported by the breadth pass; each item needs checking against its source before it becomes normative.
- English marketing often says 'MMO' for MMORPG; specialists keep MMO as the broader online-multiplayer class.
- Korea: PC-bang session culture, GRAC rating, and a long F2P item-mall design school; night-time juvenile play was legally curfewed 2011-2021.
- China: 'wangyou' (网游) as the everyday category; national licence, real-name registration, and minor time/spend caps dominate practice more than Western ratings.
- Japan: 'online RPG' / オンラインゲーム; gacha regulation and CERO matter more than subscription.
- Western Europe: PEGI plus, in a few states, gambling-law treatment of loot boxes; less PC-cafe play than East Asia.
- North America: historically the subscription boxed-product home (Ultima Online, EverQuest, World of Warcraft); F2P later imported.
- Which of these regional variation hold for the sense of massively multiplayer online role-playing game this model covers, and on what evidence? provenance
Neighbouring kinds and how to tell them apart
Reported by the breadth pass; each item needs checking against its source before it becomes normative.
- Massively multiplayer online game (MMO/MMOG) - MMO is the superclass (any persistent massively concurrent online game). An MMORPG must also have RPG character progression - classes or builds, levels or skills, loot and a role-playing identity - not merely a shared map.
- Session-based online RPG / MORPG (e.g. Diablo-like ARPGs, many looter-shooters) - Play is match or instance based; the world does not keep a single persistent society running while you are logged off, and thousands do not share one continuous shard.
- MOBA (League of Legends, Dota 2) - Short mirrored matches with a reset roster; no persistent shared world or durable character inventory that other players inhabit with you between games.
- Social virtual world (Second Life, VRChat, Habbo) - Co-presence and user-generated space without a core RPG combat/class/loot loop as the designed activity.
- Survival / sandbox MMO (Rust, Ark) without RPG class systems - Persistence and mass concurrency can match an MMORPG; they are usually classed separately unless they also centre character class, quest, and loot-RPG advancement.
- MUD - A MUD is the text-command ancestor; a modern MMORPG is graphical and typically commercially operated. Some operators and scholars still treat long-running MUDs as MMORPGs; storefronts almost never do.
- Which of these neighbouring kinds and how to tell them apart hold for the sense of massively multiplayer online role-playing game this model covers, and on what evidence? provenance

What the second pass must settle
- What operational evidence should establish 'massively multiplayer' when no universal population threshold is assumed and most activities are instanced?
- How should the registry's PHY / PHY.OBJ placement be interpreted for a game whose identity spans software, an operated service and persistent virtual worlds?
- Where should identity boundaries fall between classic editions, progression realms, regional variants and substantially different rulesets under one title?
- Which existing Vercy world models already cover persistent virtual worlds, online games or operated services, and should this entry link to one of them?
- How should the model classify borderline cases with persistent characters but session-bound worlds, or persistent worlds with only limited character progression?
