^ the game would not work using kinect, it's not that type of game.
Speaking as someone who 100%-ed the game on PS2, I don't think the achievements are *that* hard. When a secret is coming up, the background will actually flash for a second to give you a hint. It's fun and a challenging game, definitely not a chore - and hilarious!
The worst part is the stand alone dance mode, but even that just comes with practice. I've not played the game in YEARS and have already finished the normal levels, unlocked extra mode and got 25% and two costumes for Ulala's dance mode. And I really suck at games like Guitar Hero!
