Ghost Recon Advanced Warfighter is one of the best games for the xbox. I think that it even surpasses Halo 2. Not in multiplayer but in campaign mode. It is more tactical and you have to be careful. Its more toward a realistic war based game.
I will buy it when I get a 360. But I dont have one yet so... It leaves me behind. Plus the ending of G.R.A.W. pretty much leaves you to buy the second one with the ending.
So i have to admit it is fun running around behind you shooting you in the ass with the pistol on G.R.A.W. stickman. Because when we find someone i end up shooting you a few times before i actually shoot them. Also i love grenades on G.R.A.W. because they give you 12 at a time.... therefore you have plenty to waste on random assaults and makeshift artillery barrages.
