A role-playing game (RPG) is a game in which players assume the roles of characters in a fictional setting, taking responsibility for acting out these roles within a narrative. RPGs can exist in various forms, including tabletop, live-action, and video games. In RPGs, players control characters who undertake quests and may include player capabilities that advance using statistical mechanics. The first commercially available RPG, Dungeons & Dragons (D&D), was inspired by fantasy literature and the wargaming hobby and was published in 1974
