VR is fairly limited by the types of games that can be more 'successful' in a VR environment. Beat Sabre has done quite well. I imagine a game like Myst could really take on a new dimension in VR (Cyan released a VR version of Obduction but I didn't play it--regardless, it was made for PC and ported to VR).
The game either needs a slow pace (because of imprecise controls) or very broad sweeping motions. The problem with the latter is that Nintendo has been incorporating that experience since the Wii which was what? 2006 onward? So it's not like VR offers a unique way to play or control a game. It needs to sell on immersion so either porn or space/flight simulators which probably overlap the same demographic of purchasers.
