Got it yesterday and loving it. Probably not much replayability in Lego once you find everything, but still nice. Haven't tried Kung Fu Panda yet.
I have all the double pack ins. Marvel Ultimate/Forza 2, Sega Tennis/Arcade, and now Lego IJ/Kung Fu Panda. I usually wait until they hit the 14.99 or under price range to pick them up. I even have the Sega GT/JSRF, SW Clone Wars/Tetris Worlds pack ins from the original XBox.
Oh, and I DID get the Edge discount off the original price, not the discounted price, so $3 off instead of $1.50. It's not the first time I've had that happen, either.
