Weird and only vaguely relevant story to follow . . .
I had a friend who was REALLY into Stargate SG-1 and got me into it. I talked him into making a Stargate d20 character to run in D&D, and I got together a few of our mutual friends to play with him.
Unfortunately, the reason he was so into Stargate is that it gave him something to do while he was sitting around doing chemotherapy . . . and he was going downhill fast when we made the character, so we never got a chance to play before he died. He and I talked through his initial encounters one on one to get the campaign started, but that's as far as it went.
Sad story, but there's a cool aspect to it. I knew what the campaign arc was going to be about -- about getting his character (a Marine who ended up in Greyhawk by coming through a teleportal gate, in a weird Stargate accident) home. The way home was a Stargate in the basement of the Comeback Inn in the destroyed City of Blackmoor . . . a long hike from where he entered the world.
So offline, I just said that had happened, with a retired high level PC as his guide, and that he would have sold off some of his Stargate equipment before he left town to pay for the expenses of the trip.
We actually did get a campaign going, and we've been playing for a few years now. Last session, one of his two friends who plays in the campaign decided his rogue really needed to buy the "elvish hiding cloth" (camouflague netting) that's been at the magic shop since we started in 2005.
I said, "You know where's it from, right?"
The player said, "Yeah, I know."
I was thinking of having a plot where a barbarian from the north brings a video player with a message from Stargate command (from General Hammond and the PC) saying the SGC wants some more of the "magic" healing items from Greyhawk and would like to trade. But I'm thinking that's probably not a place I should take us . . .
