Why are there still no virtual reality games?

In the mid nineties I went to a VR Demo and it was quite interesting. It took place in an abandoned factory and there were hundreds of people lined up outside when I got there. After three hours of waiting I finally got inside where they had set up CDI consoles for us. I played some Dragon's Lair while watching the other participants being suspended from the ceiling. When it was my turn they put the VR mask over my head, and inserted the controller into my behind. It was truly the most exhilarating experience in my life, I still hope that one day VR gaming will gain popularity.
