I've been playing FPS games since I was ten, and, well, I'm not quite disappointed, but it feels like MW3 is missing something. I think they could have done better with the maps. And the graphics look.. off. i can't quite put my finger on it, but they just look weird.
I like Spec Ops, but, as usual, the campaign was very disappointing. especially after playing an open game like Deus Ex. and yes, they are hard to compare in terms of gameplay, but I wish the path to success wasn't so linear.
