treyarch is so much better zombies and real warfare like heads blowing off

I say Treyarch for zombies, and because IW bombed MW2.

Cod4 is still good though.

treyarch screws up to damn much and dsnt like to clean up after them selves i love WaW's zombies but the gameplay is retarded i can c the gore factor being good and i agree but for instance knifing is so stupid and so many ppl have modded controllers its not fun anymore so i pick IW CoD4 an amazing game and MW2 another great game

it depends, some have good years others bad.
cod4 was unlike anything we had seen before
cod 5 was ok but had zombies which was what but ttg on the virtual map
mw2 was good but nowhere near as good as cod 4...im not the only person that thinks this because 20000 people were playing cod 4 when i last was on.
for a game thats 3 years old that isnt too shabby
i think the only reason mw2 has so many players is because none of them know what cod 4 is like, they only play mw2...

i LOVE treyarch, but i have to give it to infinity ward because IW has a waaaaay better campaign
