There's a lot of interesting stuff going on in this new Kinect Party trailer, but what I'm most interested in is having sparks come off my high fives with other people. How great is that? I imagine that happening anyway, so Kinect Party is a way to make that a virtual reality.
I'm also digging the weird twirly body thing and being able to make it rain cash out of thin air. Double Fine has even thrown in some glowstick dubstep action as a bonus in this trailer.
It looks like I'm planning on getting a Kinect title this holiday season!
