VR is neat, but there are just inherent limitations to the tech that I just can't see them overcoming. It's incredibly immersive when I'm looking around and walking, but as soon as I begin interacting with things, it sucks me right out of it. The lack of tactile feedback and the disconnect when I pick up a massive gun in one hand and swing it around like a feather honestly ruins everything else VR does right for me. At that point, traditional games feel more immersive to me. The limitations of your physical room also cause similar problems.
A few select games built with these limitations in mind can work, but the vast majority can't and for that reason I can't see VR being more than what it is now.
