Personally, I would be quite happy paying a premium for VR in order to allow them to recoup some of the cost. And by that I mean only VR players pay extra.
I obviously can't speak for everyone else.
I agree with you on this one, yes i would pay extra for the DLC, as long as it contained ALL of the updates, i would not pay more if we can get just the extra's without the FPS which would need a lot more development work.
PS can i pay with my Arks
