Reasons others weren't picked:
Halo 3: I expect more of the same, which can only keep you going for so long. I think this will severely reduce it's reviews
Assassin's Creed: Am I the only one who thinks the combat in this game looks absolutely horrid? I was bored just THINKING about playing that combat system. I can't imagine me even remotely enjoying combat in this game after what I saw.
Uncharted: Well it's too early to be sure, but so far everything on it has had horrendous framerate drops which should have been fixed by now, and I'm now worried that they won't be for the final version of the game.
Mass Effect: I don't think it's going to live up to the hype, and I can see numerous flaws that can sneak in the game to knock it's score down below GOTY contender range. I'm pretty sure it will be great no matter what, but I don't expect GOTY level.
