Otherwise I find what you're talking about here pretty interesting but still, the kinect attachment is really a game changer, imagine paying 20 bucks to go for a half-hour into a huge warehouse where the kinect sensors watch you and let you actually walk physically around any virtual land scapes. Hook it into google street-view data and it could become quite realistic.
Seriously the dude who wrote this question just needs to hear: You're wrong. Just wrong. So wrong. Keep on keeping on because you don't see what value it has to you, but it's significantly more than you clearly have any idea. You're wrong, the end.
I have no degree, I had to study so bloody hard to get these fundamentals over so many years that I wish to death I had just got the stupid loans and done the stupid CS degree. I screwed the pooch and made up for it the hard way, don't make the same mistakes.
