Let's say that development of VR has been perfected. Movement with the headset on works, latency is so low that it's not an issue, you don't get sick, everything is working as advertised.
What kinds of things would do you want to do in VR? I'm not talking about adaptations of current things to fit a headset, I mean the crazy things you have imagined.
Feel free to describe the weird peripheral or controller that you would need for your idea to work. If VR as a platform were to take off, I'm sure these things wouldn't be too far behind.
Personally I'm just as into movies as I am into games, and am really into the idea of watching newly released (on disc/streaming) movies that I missed in the theater on a virtual big screen, assuming we get past the part where the resolution is lowered because it's split between the eyes. I don't really need the fake theater decorations and seats if it means what I'm watching looks accurate.
