You left out Rock Star (it's like GH but with drums and a microphone, too).
Halo Wars prob won't come out this year, though.
Seriously, though, the 360 has such a good release schedule for this year.
The Darkness should be sexy, too. It's cumming out tomoz. AND you left out what will probably be the game of the year on all websites - Mass Effect. Blue Dragon should be great, too, for an RPG fix.
I'm also a sports gamer, so will have to purchase all the aforementioned games, as well as Fifa 08, Madden 08, NCAA Football 08, College Hoops 2k8, NBA 2k8
