Well, thanks for considering it.
I'm not sure why some people would not be able to use it? There are plenty of VR games that show up in both sections of their libraries. Are you not allowed to provide the non-VR functionality?
Also, it'd be an avenue to generate good reviews. Not that it wouldn't get them anyway.
By "can't use it" i just mean 3DNes starts as a non-VR emulator for a very long time before fully support VR so most users purchased it to play on their PC without VR headset so they even just don't have a headset to play Steam 3DNesVR version. That's what i mean.
"Are you not allowed to provide the non-VR functionality?" : I'm allowed and i can do it. But putting everything, every feature in the same code takes a lot of time trust me. I'm eventually planing to do it but i don't think i could finish it before Steam release.
