I happen to disagree with some or your choices.
It seems for most categories you just picked what is popular now vice what had the biggest propularity and longest replay. Also for RPG's Diablo 2:TOB wasn't even mentioned. Maybe you find it doesn't fit rpg's, but then it fits Multiplayer well. Along with the free servers provided by battlenet, diablo is at least a nominee. The FPS of the year is deffinately MaxPayne, but since it was made game of the year, I find that to be better.

BTW: Diablo2 and the expansion out sold all your picks.
