I didn't appreciate the third installment very much, mostly because they didn't bother releasing it on the PC (what were they thinking?) but the franchise redeemed itself with the sublime Modern Warfare. I loved that game-the single-player was awesome (AC130 missions FTW!), the modern setting was fantastic and holy crap was the multiplayer good! I was initially skeptical when World at War was announced-why go back to World War II when the modern setting hadn't yet been fully explored-but my doubts quickly disappeared when I finally got my hands on a copy.
To call it Call of Duty 4 with a World War II skin is insulting to Treyarch because World at War is so much more than that. It's a great follow up to Modern Warfare and proves that World War II is still a viscerally charged conflict to live through. The single-player campaign is a tad short and it isn't as polished as Modern Warfare's but the action is intense, there are plenty of thrills and the multiplayer looks like it will be just as awesome. I'm especially looking forward to the Nazi Zombies mode."
