Agree with you about the conventional first person shooters. There's really only so many ways you can reinvent the wheel. As for VR tech, only a small percentage of the overall gamer market right now owns VR and right now I'm not convinced that it will ever go mainstream.
Pretty much. It won't overtake the mainstream paradigm of a guy on a couch with a controller. With VR you need more equipment, more space, and more activity for your body.
However, if & when the tech gets to a state where the equipment is not much more invasive than a pair of wireless sunglasses, two wireless self-calibrating base stations and two controllers (in whatever form they eventually evolve into) at a cheap price then maybe it'll become very close to it.
I have to say though the other thing that'll need to change is the whole 1st person aspect of it, some new way of dealing with it that doesn't try to just copy the controller version of the game, and that killer app doesn't exist yet. I had thought, before I had tried it, that Skyrim VR would be the game I'd always wanted, but in practice I hated it. Movement was like standing on rollerskates and controlling tiny motors on it, but without the inner ear feedback. Wielding weapons was just dumb, massive dual-wielded battleaxes that I was flapping about like table-tennis bats.
Like F4, I found myself sticking to what I regard as VR's natural home so far - the cockpit. Whether it be piloting, driving, flying or racing. Even there it's not entirely clear-cut, anything you're flying is basically a 3D cockpit game only, everything outside is too far to be meaningfully rendered in 3D. Driving & racing though, that's the golden spot for me. Nice 3D cockpit, and everything outside is within sensible 3D rendering distances. With a wheel the illusion is very convincing.
