Just got a Move Friday, and so far my experience with it has been pretty terrible. Didn't play it much over the weekend, but I did play some LBP2 (the game it came with) and thought it added nothing to the experience. I would have been better off playing with a regular controller. Also tried the Tiger Woods 12 and Topspin 4 demos that came on the demo disc and had really bad experiences (granted they're 3rd party, but they are on the demo disc). Tiger Woods was bad because nothing I did had any affect on the game: no matter how I swung every shot was perfect, including the put that I accidentally made while I was playing with turning the move to aim. Didn't even swing, just turned the Move, the game decided I'd swung, and it sank perfectly. Topspin was terrible because it was unresponsive but in a different way: it only recognized a forward swing, even when my character on the screen would have been backhanding (if I backhanded it just wouldn't do anything at all) and about 1/5 of the time even if I swung forward it wouldn't register it.
Getting ready to try Sports Champions and see how that goes.
