First person games as they exist today don't transfer well to VR. The issue is the locomotion problem: Moving the player in the virtual world but not the real world causes motion sickness, since they're not getting a matching input to their vestibular system. Oculus' system today is suited more for cockpit games or 3rd person games with gentle camera movement. Valve are also targetting room sized first person experiences, where the user has enough physical space that the play area can be mapped 1:1.

It is for this reason that I think that the first successful iteration of VR tech will be experienced in next generation video game arcades. That will solve both the cost problem and the space problem. You'll plan in a very big (100x100ft) room where everything physical is wrapped with three inches of foam. Things you climb on will have level drops of no more than four feet, but with a total height of perhaps twenty feet. Of course what you "see" through your helmet goggles won't be grey foam.

Will be a great place to play.

Cockpit simulators have a leg up in this department - not much movement expected in driving / flying / spaceships.

Not really. In the real world, you still moving and thus feeling acceleration. Problem therefore still exists.
