I think he meant in terms of marketing push..
And while we can argue about TV ads, I've not seen Sony push a game on the ground, here, like they have LBP.
I'm gonna guess LBP has done better relative to the userbase than any of Rare's games have on 360..(that didn't benefit from being launch titles at the very least). I'm also going to point out that LBP has been universally acclaimed, unlike Rare's titles

It's a lazy comparison to say they're like Rare, and too big a compliment for Rare as of late to be perfectly honest.
On the general topic of the thread, I think it should be doing better, it deserves better, but I don't think I'd say it's
bombed.. it should have pushed out 600k or more in its first couple of weeks worldwide looking at MC and NPD (and guessing that it's done at least as well in EU as US). That isn't
bad.
(There are some spurious claims being made about the game in this thread too, but I'm not even going to bother addressing those. This thread will be a honey pot.)
