I don't know. I certainly didn't have inflated expectations for it as it was a totally unknown ip before its release, and I find the fact that it has passed Ratchet rather staggering (though before I looked up the numbers I was thinking Ratchet would be up to 3 million or at least more on equal footing with Uncharted at 2.50 million which imo it looks like LBP is also going to overtake).
Heavens to Murgatoids.
