It has been great. Most of the Stargate setting has been during the first few years of the show, 1995 to 1998. I've had an improbable number of walk-ons and crossovers from various episodes. However, I've also tried very hard to remain consistent with the show, so I ruled out any contact with SG-1 themselves, or modern Earth, to avoid conflicts. (The android SG-1 has shown up, though.)
The most recent game was a multi-parter where they were fighting enemies on the time-loop/"Groundhog Day" planet. Injudicious use of the time device, plus an inconvenient solar flare, caused the Stargate to dump them on Earth 5000 years in the past. They had to team up with the alternate SG-1 from "Moebius" to keep Ra from taking the Stargate offworld. Finally the time-traveling puddlejumper returned them to the present. Except the jumper (really badly shot up during the episode) malfunctioned, dropped them in 2014, and then failed completely. The characters are now adjusting to the aftermath of the Goa'uld conflict, the aftermath of the Ori conflict, and the fact that everyone is 16 years older than when they left.
It's a whole new world ....
