Finding one idea that will interest everyone, especially when you have, what, a dozen people here, is going to be next to impossible. Personally I don't see a problem in saying "Well, I'm sure it will be a fun game, but it's just not the one for me" and sitting it out. There will be other games. Trying to force yourself to play a game that just isn't doing it for you is going to lead to more problems in the long run. Better to bow out before it comes to that point.
