I would have preferred the FPS. No TV show lends itself more to a tactical, squad-based FPS than Stargate.
You've even got the standard set of FPS guns ready. The standard issue Beretta, the P90, the MP5, staff weapons, Zats, the big Death Glider cannon Teal'c carries etc. Plus you've got standard FPS power-ups like a Goa'uld personal shield or a Sodan cloaking device.
