What's the deal with VR?

Trying to figure out why VR is all the rage right now even though you probably haven't tried it? A few weeks ago I got to try an pre-release "room scale" VR rig at a secret lab down in SoCal. After donning the goggles, my immediate reaction was "WOW." I was suddenly standing in another world, a world in which I could spray paint in 3D and walk through my own creations, a world in which I struggled to fix a mad scientist's robot before it exploded. The part about experiencing VR that's impossible to capture in an article, photo, or Youtube video is that you feel like you're really there.
