While I can't dispute what you saying, especially the porn
, the trick of VR for widespread gaming as we know it will be simulated motion, running, flying, without moving. My impression, this is the weakest link for using this variant of VR (VIVE) in a gaming environment like Eve, ARK, or Fallout 4. The other hurtle will be complex controls in a VR environment such as what is the norm for a flight sim.
A short but interesting article can be found in the Sept 2016 PCGamer about developers working on the obstacles of simulated motion that does not cause nausea. The term
presence was used to describe human perception associated with VR. One technique mentioned was tunneling, where peripheral vision is blurred to reduce disorientation in VR.
