VR is already here and has been for some time.
Truthfully, the cardboard Google 3-D thing you use with a phone is my favorite so far. The first VR helmets they used in Disney for attractions and the Occulus Rift gave be a headache after ~20 minutes. They're really hard on the eyes.
The $10 cardboard thing was far less-fatiguing an worked great! They're not even uncomfortable.
For gaming, though...I'm not a fan. Visually, it's "cool"...for a while. Then you start to get a bit annoyed at constantly moving your head all over the place, a bit motion-sick from never being able to stop the camera wobble, your eyes begin to focus differently and pick out both images, and all of that becomes quite distracting. I'm sure you could train yourself to get used to it, but honestly, I don't care for it. I'd rather just relax and play
