I never really feel like I
get Kinect games when I see them demonstrated.
EDIT: I think I've worked out why I find them so perplexing. I'd bet money that every single demonstration was pre-recorded and they just had hired actors to mime in time with the video. Watch this one and try to see how on earth the kids' actions line up with the video. And note how their supposedly 'in the moment' dialogue sounds so incredibly scripted and rehearsed.
