What else do we need to use a VR device? Do they cost a lot? e.g. Film Cameras were not expensive but films were. PS4 is not expensive but the games are. (to me)

You need a mean computer.

Otherwise, lots of free room if you want to enjoy room scale VR.

If you want to really enjoy driving games, you want a good steering wheel. If you want to enjoy flying games, you need a good stick. Those two can get up to $200 each.

Controllers. People are still experimenting with control schemes, I expect to see lots of different options come out before things settle down.

Software. VR is a niche market, so prices may need to be high to recoup R&D until volume is there.

According to reviews, this is awesome. http://www.virtuix.com/ $699, plus extras.

You will need a full computer with at least a GTX 970 (or an AMD r9 290) and at least an i5-4950 (or maybe an AMD FX 8350). Here's [1] a good guide, but roughly $800 for just the machine.

Then you need keyboard, mouse, monitor, internet, power...

Then you need Windows 10 (roughly $100).

Then you need games, which you will probably get through Steam [2] or through Oculus [3].

That's on top of the ~ $600 for an Oculus Rift, or ~ $800 for an HTC Vive.
