On occasion, I’ll pick up an RPG sourcebook for no reason other than to have it. Back in high school, I had a lot of RPG books for games I never got to play, like Mechwarrior or Paranoia, or Cyberpunk or Aliens. Although I had wanted to play them, my primary interest was in reading up on the settings and the mechanics that designers had added to the franchises that I loved.
I really hope they come out with a Defiance RPG. I think there’s a lot of potential background information in there that would be really interesting to have. I picked up the Battlestar Galactica sourcebook for the same reason, although I’ve tried to envision exactly how one could set a game in the confines of the Galactica and it’s fleet without it resulting in a lot of petty scenarios; I’d be interested to hear from anyone who might have played it. I think Defiance could offer a whole wealth of opportunities, however, since we’ve only heard about Defiance and San Francisco (and Las Vegas Prison). There’s still a whole lot of potential settings out there for players to create within the lore of the IP.
