Let's imagine perfect VR (the Matrix). Would it be better to play Mahjong, Poker, Blackjack, Chess, pick your favorite board game, with real pieces setting at a real table or at a computer terminal moving pieces with your mouse? I get each person might have a different answer to that.
What I like about "immersion" when done right is I just do the thing I already know how to do. Pick up the ball, cards, dice. I don't have to fiddle with one 18 buttons on the 2 controllers (up, down, left, right, press, A, B, upper trigger, lower trigger) x (left hand, right hand) .... actually 20 buttons if you include the "system" buttons on each controller.
This is one thing I hated about No Man's Sky in VR. I enjoyed it over all and never played non-VR No Man's Sky, but, while flying and aiming the gun/probe is VR, all the inventory management is 18 button based and even 25hrs in I'd be pressing the wrong button on each menu option.
Now of course, VR isn't good enough yet to do this "immersion" so often, picking up the cards, ball, etc, is just to damn fiddley. Maybe I have to put my hand 10cm past where my brain believes the object is. I've had that very frustrating experience where I can't reach the thing in VR because it's below the physical floor in my room or behind the wall/sofa/desk, so there's a lot to be fixed.
And, also, of course maybe someone will figure out better interfaces without the constraints of the physical world. For example I'm a little sad when someone makes a piano in VR given that you could invent a new instrument with a sphere of controls around you.
But, every time I play a VR game that makes me memorize which of 18 buttons to press I want to scream.
