Well, here's one huge Nintendo fan who's not at all disappointed. I see a lot of categories that Wii games just wouldn't be eligible for (online play, graphics engineering, etc.)
The Wii took home some very solid wins. Outstanding innovation in gaming? Possibly the most important category here. Outstanding gameplay design? Outstanding gameplay engineering? C'mon, let's hear it for Wii Sports!
TP still picked up story and character development, and was nominated for three game of the year categories. It lost all of them to Gears of War, but no one can deny GoW's excellence. Nintendo has done an awesome job, and I'm glad that there are companies besides Nintendo capable of producing outstanding games, too. More fun for me when I can eventually afford a 360.
