Well, the novelty of VR has pretty much worn off for early adopters and game developpers, and we're left with the reality... An expensive piece of hardware that can deliver okay, but somewhat limited vr "experiences", but kinda make most people somewhat sick the minute proper controller movement to the mix and developpers try to make full retail games out of it, unless they use somewhat gimmicky methods to trick us into not puking all over the place.
Plus , I feel like the graphical fidelity isn't there, at least on Playstation Move (granted, I don't own a PS Pro)... It was better on Oculus and HTC vive from what I remember, but still not flawless either.
To me it has the same niche appeal as 3D movies... After a couple of hours in the theater, you're pretty happy to remove the googles and get back to real life. I get the same feeling for VR. It's fun to try a new app or demo, to experience it , but I'm usually happy when said demo ends, to remove the helmet and go back to play my games on a screen sitting on a couch without feeling sick or bumping into my cat by mistake.
Maybe in a couple of years, with better screens, better optics, better graphics, perhaps a treadmill system to handle movement, it'll become something that really clicks for gaming... But for now, it feels like a gimmick more than a game changer.... Asides from VR porn... XD, I think that's what's going to keep VR alive for the next few years...
