In the early 1980s, almost every issue of Dragon would contain a role playing adventure, a simple board game, or some kind of special game supplement (such as a cardboard cut-out castle). For instance, Tom Wham's Snit's Revenge, The Awful Green Things from Outer Space and File 13 all started as supplements within The Dragon. These bonus features become infrequent after the 1986 launch of Dungeon magazine, which published several new Dungeons & Dragons adventures in each issue.
