I pretty much play VR only at this point. Any time I try a typical flat screen 3D game something is missing. The frustration of having a camera stick. The boringness of having to "press the action button" instead of just reaching out and touch the thing I'm supposed to interact it. And of course most of all the feeling of "presence". The Citadel on the horizon in HL2 (old reference sorry) is a pretty picture but nothing more. The volcano in Farpoint is 3 miles high with a 15 mile high plumb of smoke and I feel that as though I was there. It's like a picture of the grand canyon vs actually being at the grand canyon. They aren't comparable and I can't go back to not feeling like "being there".
This isn't a "gimmick" like 3D movies where they stick things in your face or throw stuff at you just show off the tech. It's qualitatively different.
If there was more content I was interested in I'd spent even more time in VR. Unfortunately there isn't that much AAA VR content and worse for me I can't take horror in VR, it's way to intense, so I probably won't be able to play the new VR Half Life coming out in March.
VR today is like an Apple Newton in 1993. Everyone laughed. Heck in 2007 PDAs where just for geeks. Then in 2008 Apple's PDA shipped, the iPhone, and now everyone has a PDA in their pocket to the point that's you'd be considered strange not to have one. It might be a while, it might even be another 15 years but VR will happen. It's just too compelling when it's good.
