MMOGs can enable players to cooperate and compete with each other on a grand scale, and sometimes to interact meaningfully with people around the world. They include a variety of gameplay types, representing many video game genres. Many MMOGs require players to invest large amounts of their time into the game. Most MMOGs require a monthly subscription fee, but some can be played for free.
The first graphical MMOG, also a major milestone in the creation of the genre, was the multi-player flight combat simulation game Air Warrior by Kesmai on the GEnie online service, which first appeared in 1987.
The first 3D MMOG, Meridian 59 is an online computer role-playing game first published by the now defunct 3DO Company and now run by Near Death Studios. It was first launched online in an early form on December 15, 1995 and released commercially in September 1996 with a flat-rate monthly subscription, Meridian 59 is often credited as the first 3D graphical "MMOG" or MMORPG.
MMOGs emerged from the hard-core gamer community to the mainstream strongly in December 2003 with an analysis in the Financial Times measuring the value of the virtual property in the then-largest MMOG, Everquest, to result in a per-capita GDP of 2,266 dollars which would have placed the virtual world of Everquest as the 77th wealthiest nation, on par with Croatia, Equador, Tunisia or Vietnam.
World of Warcraft, currently the most dominant MMOG in America has 9 million monthly subscribers worldwide, is the most popular Western title among MMOGs.
The biggest MMOG in the world is Lineage 2 from South Korea, with over 14 million registered gamers, mostly in various Asian countries.
Comparing MMOGs to other computer games
There are a number of factors shared by most MMOGs that make them different from other types of computer games. MMOGs create a persistent universe where the game continues playing regardless of whether or not anyone else is. Since these games strongly or exclusively emphasize multiplayer gameplay, few of them have any significant single-player aspects or client-side artificial intelligence. As a result, players cannot "finish" MMOGs in the sense of single-player games. Some MMOGs do have an end condition that includes awarding a "winner" based on a player's standing in the game at the finale.
MMOGs host a large number of players in a single game world, and all of those players can interact with each other at any given time. Popular MMOGs might have thousands of players online at any given time, usually on a company owned server. Non-MMOGs, such as Battlefield 1942 or Half-Life usually have less than 50 players online (per server) and are usually played on private servers. Also, MMOGs usually do not have any significant mods since the game must work on company servers.
There is a debate if a high head-count is the requirement to be a MMOG. Some say that it is the size of the game world and its capability to support a large number of players that should matter. For example, despite technology and content constraints, most MMOGs can fit up to a few thousand players on a single game server at a time.
MMOGs need large-scale game worlds and servers to connect players to those worlds to support all those players.
There are also a few more common differences between MMOGs and other online games. Most MMOGs charge the player a monthly or bimonthly fee to have access to the game's servers, and therefore to online play. Also, the game state in an MMOG rarely ever resets. This means that a level gained by a player today will still be there tomorrow when the player logs back on. MMOGs often feature ingame support for clans and guilds. The members of a clan or a guild may participate in activities with one another, or show some symbols of membership to the clan or guild.
However, the boundaries between multiplayer online games and MMOGs are not always as clear or obvious. Neverwinter Nights (2002) and Diablo II are usually called online role-playing games, (RPGs) but are also sometimes incorrectly called MMORPGs (a type of MMOG).
