Another thing I have to say: At first I was with everyone else that Treyarch sucked and Infinity Ward was the only good company. That was when Call of Duty 3 was new. Now Treyarch has World at War, which does NOT suck and remains my favorite Call of Duty, for having a great campaign combining the Modern Warfare engine with WWII setting that was fun and epic, it and Black Ops have the best multiplayer (MWII sucks with Multiplayer, and MW had decent multiplayer, but not the best), and it introduced us to zombies. Ever wonder why World at War and Black Ops'es map packs are the best selling Call of Duty Map Packs? ZOMBIES
