Oh, one last thing I forgot to mention, things just hit different in VR. I played hundreds of hours of Elite Dangerous before I tried it in VR and it was a whole different feeling. I actually endured the migraine and spent a few hours just flying around while looking at pretty things. It was awesome. That said, I don't think there would be much point in playing the game exclusively like that. Like with anything, the magic wears off after awhile, especially with games that were not designed with VR in mind.
You can't beat horror in VR though. I've played a lot of P.T. so I wasn't particularly hyped to play Unreal P.T. in VR, though I was interested. It is a much more scary experience in VR. Even knowing the triggers, my first time walking around a corner and seeing Lisa standing there made me legitimately freeze up and feel cold and tingly. The game didn't even make me feel like that when it was brand new, it just feels so much different when your brain is sorta tricked into thinking there's actually something nearby.
There are lots of other kinds of emotions I've felt, but feelings like these are truly special and unique to VR, not unlike how player agency in video games can make things hit different than watching a film. Because of this, even if I'm wrong and VR doesn't take off eventually, there will always be a very solid and dedicated fanbase, and that's a wonderful thing. The more unique ways to experience things like video games are nothing but a good thing. It's not for everyone and that's fine, no technology will ever be liked by absolutely everyone. Hell, if I could get away with not having a cell phone I'd happily do so, except maybe a cheap one for emergencies. I've never really cared for them, but they're so ingrained into everyday life, it's a pretty huge disadvantage if you do not have one. VR will never reach that level of widespread use, but I do feel like it has a bright future ahead.
