Wow! No words...
This is not gaming, this how to make a fool out of yourself publically. Okay fair enough the concepted of Natal was ooh aah, but the application not that great a Wii looks more civilised than this. Though i never really belived in the Natal project mainly cause the promotional video are way to accurate and dont take into account how the camera is positioned for motion capturing, this video just made me like the PS3 move alot more, cause its practical application is reasonable and makes you less like a dork (not refering to anyone). This will not do well with hardcore gamers at all just because the controller a much more preffered interface that this.
Evil meet my Sword. Sword, meet Evil!
