My verdict on MW3?
SP: Took me three hours. Shortest of the three games...way to short. Had it's moments of fun action, but still...
Graphics: Somehow, they manage to make the game look even
worse than its predecessor, which I suppose is an achievement in itself.
Sounds: God Awful. Apart from some heavily scripted parts of the SP.
MP: God Awful. Just like MW2.
Co-Op: Here is where I'll get my money's worth (as I expected). Tons of fun actually, since you are cooperating with someone, rather than the dreadful business of MP. As said in WTF is MW3: "There isn't really any teamwork, you just let the other guys go ahead so they get shot first..." Had great fun so far, expect to spend quite some time at this mode.
MP really is a joke, just as MW2. The fact that you have to level up just so you can play CTF for example...
