Additional information: This looks really cool! Imagine controlling your favorite characters with your own body, transpose yourself into the game through the character, have better precision and better movement. Well it all depends on the game you're playing because not all of them will allow you to move freely. Special designed games for Kinect will probably give you a better experience.
