Actually because of the way your brain and body are linked: a 3D "walking around" simulator, (while sitting stationary) is currently the worst possible VR experience.

The best, is piloting a machine - car, plane, etc. You're in a seat, like your real body is.

You're waiting for the: experiencing a X-Wing in motion while in a dog fight destroying TIE fighters over Jakku, R2-D2 beeping in your ears demo.

If you get the chance try Eve Valkyrie on a DK2. It is one of the closest, currently existing, demos to the one I described above.
