Yup, there are mappings for hand gestures, and unless you find a good profile *YOU* have to set that up, and maybe share the profile YOU worked on for others to enjoy. To avoid punching my wife or stepping on the house-cat, and ALSO because I lose keystrokes I'm already familiar with, I skip controllers and just go for keyboard play with the VR.

I'd say there's zero chance for this to go VR. Gameplay is made without VR in mind, and VR is a comparatively tiny audience. There's the mod too for those who don't want to pay for VorpX, but if you are doing lots of unsupported games AND have VR, VorpX might be a useful part of the tool-kit to have on hand.
