Personally, I can't really care for what Gamespot chooses. After all the rap they took last time, plus their new selections for Special Achievements (MGS4 beats Crysis Warhead in Technical Graphics department, they say), this is really not the best site to get an honor from.
Although another "Best of 2008" badge on Sins of a Solar Empire wouldn't hurt, even if it is from something as bogus as Gamespot.
