massively multiplayer online game

Internet-connected group play

A massively multiplayer online game is a video game that supports large numbers of players—often thousands—interacting simultaneously in a shared virtual world.

The genre emerged in the late 1990s with titles like *Ultima Online* and *EverQuest*, reaching mainstream popularity with *World of Warcraft*.

Usually abbreviated MMO or MMORPG (when emphasizing role-playing elements): I lost a year of my life to that MMO.
