Text-based game in the context of "Multi-user dungeon"

Role-playing video games, also known as computer role-playing games (CRPG), comprise a broad video game genre generally defined by a detailed story and character advancement (often through increasing characters' levels or other skills). Role-playing games almost always feature combat as a defining feature and traditionally used turn-based combat; however, modern role-playing games commonly feature real-time action combat or even non-violent forms of conflict resolution (with some eschewing combat altogether). Further, many games have incorporated role-playing elements such as character advancement and quests while remaining within other genres.

Role-playing video games have their origins in tabletop role-playing games and use much of the same terminology, settings, and game mechanics. Other major similarities with pen-and-paper games include developed story-telling and narrative elements, player-character development, and elaborately designed fantasy worlds. The electronic medium takes the place of the gamemaster, resolving combat on its own and determining the game's response to different player actions. RPGs have evolved from simple text-based console-window games into visually rich 3D experiences.
