I have yet to see a VR game I would pour a ton of time into. Right now I'm playing WoW, Zelda: Link's Awakening, and Mario Maker. Perhaps someday I'll be able to play a game like WoW in VR, but we're not there yet. Zelda and MM wouldn't play well in VR. So where's the "killer app" (ugh)? I imagine it will come, but I haven't seen it yet, which is why my headset is collecting dust.
Don't get me wrong, I'm excited for VR (I was an early adopter and even toyed around with a dev lot for a while). Problem currently is that the library of games I want to play just doesn't exist.
Like I just bought No Man's Sky since they added VR. I thought I'd only play it for 20 minutes just to see the algorithmically generated worlds but I ended up spending 20 hours in it in VR. I felt like a little kind full of wonder and glee everytime I jumped in a ship and took off. I felt like a little kind building a camp. I felt like a little kid when I found a water planet and launched and rode a submarine. Same with drilling through an entire mountain. It was amazing to "be there" instead of "looking at a picture of another character being there" (normal 3D games not in VR). It's not a great game yet IMO but just being in these situations in VR blows me away.
Breath of the Wild is my favorite game of all time but I was disappointed it was not in VR once in a while. I wanted to just be able to look around with my head not the R stick. I also like VR games where controls are in the world, not the buttons. Like reach over your shoulder to grab your sword and hold up your shield not press Y and old R.
I'm actually surprised Blizzard hasn't made VR WoW and hasn't either added facial capture attachment or pushed Valve/Oculus for one. If there was a low-res device that could capture your mouth shape and eyes so that your in game character could match your expression I'd think the enjoyment/addiction level of playing WoW would be 10x whatever it was at WoW's peak.
I agree the good content isn't there for VR yet and there isn't enough of it. I also agree there may never be a big market for many reasons. But, the moments VR's strengths shine I'm blown away and can't go back.
The only uncapped VR experiences I've tried so far were Beat Saber, Rec Room and VR Chat. At the time of writing I'm at 99 hours of Beat Saber.
Not the GP, but in my experience, yes, they have. Problem is none of the games we want to play are available. It's a neat sideshow, but the headset gets stored away soon enough and we go back to the games we want to play.
