If you are into combat sports and such that include running around and shooting up a storm, this would be the ultimate gaming accesory. Deffinatly check out the site, I would love this thing in my room for say socom or something along those lines. And here's a way to get parent's to buy it for yo,although its expensive, " It's not just a game, you run in it and everything, so this way, I not only learn teamwork and problem solving which are useful i nteh real world, but I get excercise at teh SAME TIME!!!! PLEAAAASEEEEEE."
