Campaign settings are fictional universes which serve as settings for role-playing game or wargame campaigns.
This category is solely for fictional universes that were originally or primarily intended as game settings. Many popular role-playing games and wargames are set in fictional universes from literature or film, such as the Star Wars, Star Trek and Middle-earth universes - that does not make those universes primarily campaign settings. (For a list that includes adaptations of settings from literature and audiovisual works, see List of campaign settings.)
