Off topic but for the people who have played with the Oculus Rift & TrackIR. Is the Oculus worth it? Better than TrackIR? or not comparable?
As has been said, it's not comparable. You can look behind you and tilt your head in any direction you want.
The Developer Kit still has a lot of downsides, most notably the bad resolution and the resulting Screen Door Effect, but all that is not too bad. The feeling of being in a game makes more than up for that.
The Rift is and will be perfect for racing and flight sims! Dogfighting with it is a treat.
I can't see it having a good stand with FPS though. The nausea you get from it is a real killer, when your body moves separately from your head by more than, let's say, 100DEG you feel it creeping up on you in under a minute. I have a tough stomach, but that got me close to vomiting. It's really bad, when you are expecting to walk straight, but your body is off centre by like 1-3DEG and your head tries to compute the different vector! ^^
