We waited a long time to rent this game due to availability. There's a weird dance lessons thing, which from the few I saw told you nothing about actually playing the game. I found the best part about the game was unexpectedly knowing that the PS eye records your performances in 30 second sections and a few photos and reveals this to you after playing a certain song. The selection of songs seems to be really limited considering the fact MJ was such a huge hit and around for a very long time, in regards to performers careers going. Definitely not worth a buy, but a decent rent.
I would give this game a 10, because it is incredibly fun, but it only gets an 8 because I wish there was more of a "game" to it. The unlockable content is pretty disappointing, and it could have been more like career mode in, say "Beatles Rockband", for instance. On the other hand, having played this game on the PS3, the XBox 360, and the Wii, the PS3 definitely delivers the best overall experience. Super fun aerobics workout!!!
