Hmmm.. there are a lot of interesting Xbox games, but I have to go with Stubbs The Zombie, that game is pretty fun and well, interesting. The most boring game I've played in my Xbox was L.A. Rush. I mean, the game is okay, but playing it right next to Need for Speed Most Wanted and Forza, well, it doesn't hold a candle, even if the game is open world I just can't get into it.
