Is it possible to play Kinect Joy Ride with wireless Xbox 360 controller? I don't own Kinect yet.
No. If a Kinect game has the purple case with Kinect on it (which Joy Ride does), you have to have the sensor to play the game, see http://en.wikipedia.org/wiki/Kinect#Software
I've only played the demo version of it that came with the Kinect, and it doesn't appear you can do it with a controller.
Frankly, however, this game would be extremely lame if it wasn't for the motion-sensing no-controller aspect of it. This game is absolutely centered around that gimmick and really doesn't let you control too much of the game. Acceleration and Braking is all controlled by the AI, the controls you are given are limited to steering, speed-boosting, and a few tricks on jumps.
