Undoubtedly a fun little platformer. The game boasts respectable gameplay, and an impressive audio-visual combination, as well as a comical plot from the folks at Dreamworks. There’s plenty to do in the levels, and plenty to unlock for a second play through.
But even with the mini-games and ability to replay the levels, I'm not 100% sure how much of an interest the game will hold. I wonder if after 2-3 days with it even the kids will get bored. For that, I say renting it is the best bet.
