A massively multiplayer online game (referred to as an MMOG or simply an MMO) is a game, usually on a client-server model, intended to be played by large numbers of people simultaneously in a persistent game world. Most MMOGs are MMORPGs, though there are also some first-person shooter MMOs and other genres as well.
