role-playing video game, electronic game genre in which players advance through a story quest, and often many side quests, for which their character or party of characters gain experience that improves various attributes and abilities. The genre is almost entirely rooted in TSR, Inc.’s Dungeons & Dragons (D&D; 1974), a role-playing game (RPG) for small groups in which each player takes some role, such as a healer, warrior, or wizard, to help the player’s party battle evil as directed by the group’s Dungeon Master, or assigned storyteller. While fantasy settings remain popular, video RPGs have also explored the realms of science fiction and the cloak-and-dagger world of espionage.
