^No but a part of it should be how well a game will stand the test of time, how much long term effect the game will have.
We know NSMB Wii will have a much greater and longer term effect, it'll bring new people to gaming and will still be a game people will love to play a decade from now, Uncharted 2 is nice, but will be overshadowed by future games, like Uncharted 3, and forgotten.
Game of the year should be a game that will become a classic, NSMB Wii will certainly become one, Uncharted 2, much less likely
