But every player of Pokémon Go that really tries to play the game not just for 30 minutes disables the AR camera first to save battery and because it doesn't add value. People using Pokémon Go with the AR cam enabled are young kids (it's funny) and Asian tourists snapping photos with Pokémon in front of landmarks and tourist spots.

I second your remark on motion sickness. And VR cuts the user/player from the real world, which is a social annoyance outside your own living room.
