You don't have to develop special motor skills to grab stuff. It's not 1994. The new controllers are intuitive, especially the Touch controllers from Oculus. If you can pick up a can and walk around in reality without stumbling, you can play a VR game. You don't even need two eyes - real-time head tracking (positional, not just rotational), is in my opinion, the real key to VR.
Also... room-scale, even the new controllers, is all completely optional. I don't actually have Touch controllers or a second sensor yet. But have faith in this hardware because I've worked with it before. Before my current job, I worked with the CAVE at my university. A CAVE is basically a roomscale VR setup for wealthy university computer science programs.
As for my computer - it wasn't just for that. it also serves as my workstation away from work - my job involves working with very very large 3D building models, point clouds, etc. In my spare time, I do some creative modeling, rendering, and programming.
But back to VR... it isn't just good for games, it's also good for business. The company I work for is procuring another Oculus headset just for me to use, which will allow for prospective clients to fly about and interact with their building before it's built, hopefully increasing the chance they will select us to build it. Before you say that's crazy - it's a genuine application. I know it because I've done it. It's why I have this job to begin with.
As for your last comment, Mr Anonymous, 3D is kind of my jam... without which, I'd truly be joyless. Not much can be done about the anti-social bit though... you've got me there. I can put on a good face and interact like a normal human being - but at the end of the day, I like being alone. You can look down on me if you want. Just know that while you're out there being a social flower and spending all your money, I'm probably working.
