I agree 100%. Best CoD out of all the newer ones. It was my first CoD and it was fun to play. BO and MW2 get boring really fast to me. It was the only one I went through to get to legit 10th on. Also, the maps on WaW were the best maps on any CoD. Actually thinking about buying it again and playing MP on it when I get bored of BO/ other games.
This COD is up there... personally i love all of them.. and every level is jam packed with action... treyarch did a great job plus ZOMBIES!!!!!! its hard to beat!! i think tied for best with COD 4
