Yeah, I love the StarGate universe! If I were GMing I would adapt either Mutants and Masterminds 2nd Edition rules (power levels limited by race and tech access), or GURPS 3/ 4. The really good news is that we don't actually need to GM, as I have the Mythic Game Master Emulator pdf. Furthermore, while some shoot-'em-up is a required given, I kind of wanted the team(s) we saw to do some more culture-building or tech-helping. I always thought that there were a lot of story possibilities for that kid who has all of Jack O'Neill's memories...
