Brad Shoemaker from Giantbomb.com writes, "I don't think I'm quite ready to give up Call of Duty 4's endlessly addicting multiplayer just yet, but nevertheless, the Activision annualized release machine will trundle on later this year with Call of Duty: World at War. To their credit, they've at least favored a unique subtitle this time over the same tired sequel numbering, which was getting a little excessive year after year. They've also given the hardworking developers at Treyarch a chance to sleep occasionally, since the team has had a full two-year development cycle to crank out World at War. That's positively languid after the sprint that apparently was Call of Duty 3's ludicrous eight-month production schedule. Happier developers make better games, right?"
