A massively multiplayer online game (MMOG or more commonly MMO) is an online video game with a large number of players on the same server.^[1] MMOs usually feature a huge, persistent open world, although there are games that differ. These games can be found for most network-capable platforms, including the personal computer, video game console, or smartphones and other mobile devices.

MMOs can enable players to cooperate and compete with each other on a large scale, and sometimes to interact meaningfully with people around the world. They include a variety of gameplay types, representing many video game genres.
