Roleplaying archives are web-accessible collections of game-related files, including, but not limited to maps, adventures, character sheets, and netbooks. Whereas many web sites showcase the gaming philosophy or experiences of their creators, archives emphasize quantity and diversity, collecting files from many sources and authors.
A campaign is a series of gaming sessions using the same characters and settings in order to create a larger ongoing storyline. Many Dungeon Masters create entire imaginary worlds for their campaigns.
