Hi Haunted, you would be wrong. I owned an Xbox 1 with Live, and have owned a 360 since launch. I even borrowed a Wii for a while this year. I just have really weird tastes, apparently, that cause me either not to play certain games, or just to flat-out hate them. My two favorite games on 360 are Forza 3 and Trials HD, but they were released a while ago. I hated Limbo (hard to like if you have a 2yo kid, same reason why I've shied away from Heavy Rain). I can't try Kinect (don't own it, not enough space). I can't get into most shooters. I don't play many sports games. I've hated Mario and its aesthetic all my life. I love Kirby's aesthetic, but not out here in Europe until Spring next year. It doesn't leave much.
Don't suddenly expect to see Mass Effect 2 on the list next year just because it comes out on PS3 then either. I did play Final Fantasy XIII but didn't like it enough to come onto this list. And I played 1% of GTA IV and hated it. So you'll forgive me for not jumping onto Red Dead either. Hated Bayonetta. Couldn't find anything to like about Alan Wake (my wife is the Stephen King fan, but you'll have to remove a LOT of shooting before she'll try something like this).
Oh, and my PC that is currently worse at running multi-platform games than my PS3, will be capable of gaming more or less starting tomorrow. So who knows if I'll try Civ 5 or Starcraft then though I played so much Civ back when it was originally released that I haven't found the patience to get into the modern releases (I keep trying each time though). And I also have a PSP, no games from that either.
