Simple works for me, I'm still learning the game's nuances, but introducing other things is fun from time to time. One game that was run by the old GM on our board was one with a Serial Killer, who didn't win with anyone but himself, but could make a night kill every other night.
The one quibble I have with the office space game is that the items have abilities that aren't spelled out. I would have had no idea the rope could protect someone. Overall, it's been very well done, though, and I hope the good guys win.
