I played a VR space game at Six Flags as a kid and it was pretty cool, when you turned your head, the goggles showed you different parts of the cockpit. You sat in a chair and had to look at ships to aim at them and then shoot them (your head motions controlled a cursor). I remember my head over my shoulder and seeing that the chair you sit in is also rendered in VR, pretty well thought out.
Thats my main issue with these, and why I've never bought one - it isn't a new idea they have made screen glasses for a long, long time. But besides the price, I don't want to buy one until I can try it because I doubt commercial grade glasses will have a very good range and precision for when I try to look around in a VR simulation or FPS, or whatever else I might want to play on it. I don't want a shaky image or bad tracking or small viewing range.
So I've been waiting. Someone is bound to make em good someone day but I'm just leery.
I know why Chad really wants these, he thinks they will make him look almost as cool as the guy on the ad.
