Bought it and... son, I am disappoint.
1) You can't hold and relax individual joints.
2) The "boost" power by shaking the controller is a pointless gimmick.
3) Every color is available from the start so there's nothing to work for.
4) Not much customization. I didn't expect textures, but it's definitely "Toribash Lite".
5) The most popular modes (like aikido) are missing and instead we get ones nobody plays.
6) The defaults for the modes are entirely wrong.

I haven't bothered trying to play online. Number 1 was a deal breaker for me.
