Have you used a wii? If so how do the controls compare? Personally, I like the idea, but hate how it works with the wii.
Got a Wii as well.
Wii doesn't compare to the Kinect since you don't need to handle the controller.
Example: on a workout on the Wii, you are able to cheat by minimizing the motion etc.. With the Kinect, you have to follow through the motions since it captures your camera image. Seeing yourself on the screen helps you to immediately correct form etc. which is also very helpful.
Takes a bit of getting used to but it's way fun...
I had originally bought a Wii with the family in mind but with the controller etc. the kids play it from time to time but WE never got into it. With the PS3 we played Guitar Hero etc.. I like that with the Kinect I can interact with the screen without holding the dang controller.
Personal choice... The PS3 is just as good if not better for games that use a controller... For family 'fun' so far - the Kinect is way ahead...
