The Stargate SG-1 Adventure Game

The Stargate SG-1 Adventure Game was an unreleased roleplaying sourcebook written by John Tyne for the West End Games D6 system. Written in 1998 whilst West End Games had the Stargate SG-1 roleplaying game license, the book had to be cancelled when West End Games went bankrupt and was never picked up when Alderac Entertainment Group took over the license and changed to the d20 system. John Tyne, however, released what he had written of the book on his website several years later.
