It never occured to me that you could revoke a game of the year award. Thats what makes the guys at Penny Arcade so humorous. They think of things that no one else would. From their news post:

In other news, we hereby revoke 2004 Game of the Year status for Blizzards “World of Warcraft,” effective immediately.

It seems they are pretty ticked off at the constant emergency maintanence required by the more popular servers. If you want to read an interesting tirade, drop by Penny Arcade and read the full scoop.
