I had never even heard of it until now so I googled it. It's been around since 2003 apparently. I guess it just recently became popular if it's just NOW being featured on TV. Like I said, I've never heard of it and I like to think that I'm not THAT out of the loop.
I checked it out. It looks cool if you are into virtual reality games. I've tried them but I'm not good at them so I will not be participating in this one.
