The Oculus and its ilk happen to work great for certain classes of games - just about any vehicle-based simulator (racing, flying, etc.) where your immediate reference frame is static is perfectly suited to a 3D headset. I hesitate to call it VR in that case, as I feel like freedom of movement in the real world is wrapped up in some definitions of VR. For the things I care about, I essentially see 3D headsets as an evolution of the TrackIR concept (https://naturalpoint.com/trackir/)
