Just like it was awesome how CoD went back to WW2 after MW1? (World @ Warfail)
Actually, in my opinion, World at War is the best title in the series, having played all of them. COD4:MW is a close second, and COD:BO is 3rd on my list. Modern Warfare 2 however was such a complete joke in regards of its multiplayer. World at War had amazing maps, nothing overpowered, had tanks (never really used them, normally never play anything non hardcore and tanks wern't in hardcore). Good weapon set, although the MP-40 should have been pushed back about 15+ more levels to unlock in my opinion. Also, the War game mode was by far my favorite part about that game. That being said, I'm now pretty much a Battlefield person now because of BC 1 & 2, and cannot wait for BF3.
