GURPS Stargate SG-1


These are some notes I wrote on adapting the Stargate SG-1 TV series to a GURPS game. They are far from complete, but I think they at least allow you to kickstart a campaign.They are heavily based on John Tynes' work for a now aborted D6 Stargate RPG game and on my own understanding of the show's mythology.

I hope you enjoy it. And don't forget: Stargate SG-1 belongs to MGM/UA

Unusual Background (Former Goa'uld/Tok'ra Host), 25 points
A character with this advantage was, at some time, a host for a Goa'uld or Tok'ra (most likely the latter, since he or she is still alive). As a result, the character can sense the presence of a symbiont when in close proximity of it. Unfortunately, the reverse is also true, and symbionts can sense that the character was once a host. Through the use of artifical methods, the character can access his former symbiont's memories. The character can also wield certain Goa'uld artifacts like the Ribbon Device.

    This skill represents a detailed knowledge of the Goa’uld, encompassing everything presently known by SGC. Successful use of this skill could allow the user to pass for a Goa’uld servant or recognize and understand a Go'ald ritual or event.
