A gave Second Life in VR a...Second Try. Now that I understand how the controls work, I gave it a real chance, and, you know, once you start treating it as a "nine panel monitor" and realize the center panel is where you should be looking, it's actually kinda nice.
Checking out some of my usual haunts, twice I got hit with vertigo from looking down a cliff. And visiting a friends skybox, I purposely jumped while looking down, and...yeah. 🙂
So, it's very clunky, but if you can touch type (or prefer voice) you can use it for 3D. Not a VR experience, even in mouselook, but pretty decent 3D.
