There was a VR headset announced for Japan for the PS2. I don't know what became of it, if it was even ever sold. It was a Sony product.

Fighting games have had stand-up and kick and punch things since genesis, at least. I have an ad for one. I can't picture it working well.

For a fighting game there should be a control system that works somethign liek and analog golf swing and deciding which attack to make together. I want to be able to more precisely coordiante characters. It could work to open up a lot more in the line of fighting games or even RPGs.
