At the moment the big problem with Rift appears to be that it's almost too immersive, to the point where your body expects to be able to do things that the hardware doesn't cater for yet. This is especially evident in first-person games where you want to be able to walk, run, jump and strafe but currently still have to rely on a controller (until stuff like the Omni becomes mainstream at least - http://www.kickstarter.com/projects/194 ... orite-game
However I can see it currently being perfect for driving games like Forza Horizon where you want to be able to look around a vehicle interior and have peripheral vision through your windows, in mirrors etc. It's not going to feel quite so alien sitting prone in a chair with a wheel remote when your virtual self is basically doing the same thing, leaving you free to look around without feeling nauseous. Now if only they can reproduce the smell of the Amalfi Coast and the feeling of a warm sea breeze on your face..
