Played Black Eyed Peas Experience for Kinect and it was pretty fun. The moves were very confined to a box, so not much leg movement, but it had a nice sense of dynamicness. There are little bright stars where I think it's really wanting you to hit the beat. I didn't find the feedback that useful, and had to figure out what I was doing wrong mostly on myself. I think I agree completely that if you like BEP music, it's a fun game, because they really have a lot of very heavy beat, dancable stuff. If you don't like their music, well, stay away from this game. The dances are also high energy, so you do get your body moving, which is nice.

One thing I didn't like is there's this big long intro where your avatar (mine was wearing heels, but was other wise a hot version of me) strolls in basking self indulgently from the fame of being the one chosen to dance with the computer-BEP.

Apparently it had a mic mode too. so I think I need to purchase a wireless mic for my xbox now.

Dance Masters is still the winner on the dancing games, but again, you kind of have to be able to tolerate benami music to enjoy it.
