I played it at a friend's house with five women who don't game. They were all hesitant in trying it out, but after my first embarrassing turn at "Dance Central," I couldn't tear them away from it.
They remarked that it's way cooler and more fun than the Wii. One of them even got an Xbox 360 AND a Kinect a few days later.
It reminds me of when I first got my Wii: It got hot women playing video games, and loving it.
I only really cared for "Dance Central" myself. Kinect Adventures had some fun games, but it was hit and miss. Kinect Sports wasn't even as fun as Wii Sports.
Just for the novelty and party factor, I'll definitely be getting one myself, but either after it drops in price, or if "Child of Eden" and "Project Draco" kick ass.
