I think its going to be MGS4.

I love this game. I got all the achivements in just 2 days. But I really hate the ending. It was a total disaster. But fighting demons with your Team was awaesome. I want more. I wish that there was a sequel and maybe Doom 4 hehe. Gears of War 2 is totally going to ROCK!!!

OK this my list of games that I want this year. These games is only for the 360. So this is my pick. I'm also going to get Dark Sector, Viking Battle for Asgard, Alone in The Dark, Soul Calibur 4 and lots more. Now I'm playing Condemned 2 Bloodshot.
