I'll wade in just to say that even made for VR games require some level of abstraction. Haptic feedback isnt very good at making you feel touch and movement. It is still weird to use a motion controller to move a solid hand that has no finger tracking, and so on.
Using a gamepad to play games adds just another level of abstraction, seated rather than roomscale adds another level , and so on.
VR with motion controls and roomscale is very good but I have had just as much fun and been just as immersed playing seated games in vorpx or mods. Lets not kid ourselves about how real VR is right now. It's still just a cool, novel way to play very unrealistic games.
