Not a game people here would play, but a neat technical achievement.

You're right, that's pretty neat, especially since I didn't think Kinect was capable of that

It doesn't show six players playing.... also, does it mean six total or six simultaneous?

He said 'it is playable by up to 6 people if you have big enough of a living room'.  To me that says simultaneous, but he didn't use the word 'simultaneous'...

Awesome thanks. I didn't turn on volume, lol, at work. If this was technically possible, I wonder why dance central limits itself to only two players. Games like that are purely party games and more players === far better experience.

the skeletal tracking only works for 2 people but it was spec to track 4 players (just dance) so i assume most of it is simple tracking eye toyish.  difference  kinect could still pick up depth

"The tech is almost as jaw-dropping as the graphics: Double Fine has somehow worked out a way for up to six different players to appear and play in every scene, and while only the front two actually have skeletons rendered, even the back players can do things like move around and point in various directions (at one point, each player gets a platform to fly around 2D space, and can point to throw spells at each other). One underwater level even monitors the players' faces, to create air bubbles that float up from mouths when they're open."

That's most impressive.
