Well, World at War's online multiplayer is enjoyable, though I much more enjoyed Call of Duty 4. I do prefer World at War's maps, though; I think. Perhaps. Maybe. World at War plays like the offspring of Bad Company and Call of Duty 4. Revisiting Call of Duty 4 emphasizes this. But yes, only get World at War if you're going to use its online multiplayer. Its story campaign mode is rubbish.
