I recently was allowed to play with the Kinect sensor at a technical conference. I will go over a quick summary of comments:
Overall: The experience was amazing, I would definitely like to try some games out (and will do so on Nov. 4th)! I expect some game genres to benefit much more than others. I can see dance, fitness, action, adventure and RPG's as the big winners. Fighting might be challenging, you would need somewhat of a physical condition that can take the punishment. I can foresee using the Kinect as an "augmented reality" sort of device, where the use of another device in conjunction with body movements can certainly be very interesting and fun. I can definitly see how Wii can move around and use other sensors to augment the player's experience, the same as the Move. I haven't tried the Move yet, and it would be an interesting trial. I can honestly see people making their own gear to play Kinect games, since it would be cool to make your own physical item, to enhance the experience, not that the experience is on a whole new level as it is. As developers continue to learn how to leverage Kinect (and I hope they eventually open this up for XNA Community Content), and combine this with the Live experience I can definitely see the lines between fact and fiction blur... Now I need the 3D glasses that go with the Kinect in order to get the job done!
