Microsoft's Kinect is currently the talk of the town. With its full-body, no-controller input, people are finding that for the first time they can play a video game without needing a controller. Those people obviously weren't around in 1993.
If they had been, they'd know that Kinect is actually the second attempt from a major video game manufacturer at selling a full-body, motion-sensing peripheral. The first came from Sega, and was released in 1993.
