haha, yeah treyarch may have perfected it, now they need to move on, you can just keep perfecting the same setting for a game cause it will be pretty much like playing cod3 all over again. modern warfare can probably last alot longer than a wwII based game. due to the fact that its war setting is placed in just about every kinda of them how cod was pretty much back woods running through trenches all through the game, few houses here and there.
