I got a Kinect for Christmas. And, to be honest, I think it's brilliant. Yes, hard core gaming rar rar rar, but as a tool for parties and the like it's up their with Singstar. (note, your opinion on this will probably be directly related to your opinion on Singstar). I loves me some Rock Band, but all the instruments take up far more space and are much more difficult to transport around.
So, anyone else got it? Or Move? I'm undecided on that. On the one hand, it's a much more advanced Wii. On the other, it's just a more advanced Wii. It probably won't require a living room the size of an aircraft hanger though.
