I love the game.
I think honestly that Treyarch is the best COD developer, IW was good on 1 and 2, and I agree that COD4 is ONE OF the best Shooters ever made. But WAW and BO, take the role of best COD's. The Zombie mode, the carnage, the gore, the weapons and especially the storyline in BO and the over all feel and mood. The only major difference is graphics.
The only major beef I have is that the game is so buggy its like an ant hill. FR bugs are alll over the place, and it kills the multiplayer totally.
Once they fix it, this will easily be "must buy" material.
