I Like It, But...
I'm in the camp of people that wonders why they changed it from the version that was released on the Wii/PS3.
Compared to Dance and Performance modes, the moves on the first iteration seemed more accurate and truer to MJ (which is still not saying much when you compare it to the videos or concerts.)
I also liked being able to sing and dance every song separately for the trophies (and I did get the platinum in case you were wondering). Performance and Master Performance don't cut it, as you neither dance nor sing for the entire song.
Now, if Master Performance had you do BOTH the entire time, THEN I would be much happier.
Still, I am enjoying the game. I just wish Kinect would register better, although I'm not sure if that's because it's too accurate or not accurate enough...
