I ran a Stargate D20 RPG game a while back, called Stargate SG-4, and very much missed GMing in that universe. For a long time, I wanted to make a D6 version of it. This also afforded me an oportunity to codify and collect all the rules that I use in Star Wars D6 3rd Edition, while putting a Stargate spin on them. Once the rules were created, I ran a shortlived game Called Stargate Aurora.
