Having owned and played on almost every game system there ever has been, includng colleco and an atari lol, I would say go for the xbox360 with kinect. They offer most games that are available on Wii, and Wii fit is ok for excerisizing, however the kinect requires full body movement. You get a much better work out with the kinect than you do the Wii. I know my 9 yr old hardly ever touches his Wii anymore since geting the Xbox, and my 32 yr old husband is also pretty much only playing on the xbox. My 50 yr old mother also plays on the xbox she bought for herself after playing on ours. So no matter the age, Xbox has something to entertain you!
