Roomscale was great but my beliefs held true. A couple feet is great so that you can bend around and stuff but walking is a no no. Plus I pulled the cable out of the PC by stepping on it haha.For sure.
It's better than nothing, but makes you really wish full scale VR was possible.
World Scale VR is still a problem.
There's a ton of research going into it, so hopefully something comes out of it.
I've seen "comfort mode", "stability cubes", there's also a bunch of other just visual changes to help with nausea.
There's also the Omni and probably some competition in there.
And a lot more.
