Each issue provides four to ten self-contained pre-written, playtested game sessions, sometimes called modules. Gamemasters can present these modules to their players as written, or adapt them to their own campaign setting. By providing ideas, plots, villains, maps, monsters, and hooks, it can save gamemasters a great deal of time preparing a game for their players.
In late 2002, Paizo Publishing acquired publishing rights to Dungeon as well as its sister magazine, Dragon magazine.
