It's amazing. I never played the first one because usually I find Tom Clancy anything makes me fall asleep from pure boredom, but this game really surprised me. I think I'm almost done with the campaign, it's very short and I only bought it last night, but it's very fun as well. I can't wait to play on Live, I love BF2, and it's suppose to be a more sophisticated version of it.
I think it's one of the best games I own for the 360, at least in this genre, although I absolutely hate Gears of War so it helps.
