I'll go with Gears of War 2.
It is pretty shocking how far it still is, though. It's a prime example of how large launches don't necessarily guarantee higher sales, as the sequel sees weaker legs. I'm looking at Modern Warfare 2 - people were extrapolating the sales from its first week (assuming it will have stronger legs than MW1, even), I think they're in for a big disappointment.
