A
campaign setting is usually a
fictional world which serves as a
setting for a
role-playing game or
wargame campaign. A
campaign is a series of individual
adventures, and a
campaign setting is the world in which such adventures and campaigns take place. Usually a campaign setting is designed for a specific game (such as the
Forgotten Realms setting for
Dungeons & Dragons) or a specific genre of game (such as Medieval fantasy, or outer space/science fiction adventure). There are numerous campaign settings available both in print and online. In addition to published campaign settings available for purchase, many
game masters create their own settings, often referred to as "homebrew" settings or worlds.
