Stargate SG-1 (roleplaying game)

Stargate: SG-1 Roleplaying Game is a role-playing game based on the TV series Stargate SG-1, released in 2003 by Alderac Entertainment Group. The game, based on AEG's Spycraft, uses the d20 System. Since Sony did not renew AEG's contract to publish the game, it is now out of print.
