VR most likely won't take over the gaming industry simply for the fact that it's hard to program games in VR. While yes immersing yourself in a game and being part of it is one of the coolest things imaginable it's just too much work for it to go full on taking over the place. PC and console games are probably going to stay on top since they're a lot easier to make and reach the widest audience. Not everyone has a VR set but a PC or console is needed to run VR in most cases so the general audience is most likely going to stay smaller since not everyone with a PC or console has a VR set at the ready. As for what I said earlier about the workload, that would probably be one of the biggest problems besides the audience factor. Hardwiring movement directly to the movement of a person is bound to break some things, this coupled with the fact that pretty much all VR sets don't have remotes with joysticks so movement is going to be hard to implement without them.
