I agree i’m glad you said this (came here to post this, lol). Its wrong to rule something out that could be amazing for some people, just because it makes some people sick. (i think)
Just provide users with options, and have sensible defaults.
There are things you can do as a dev to help people in this situation as well, it’s not all so clear cut.
Things like reduce fov. Reduce movement on z axis in your level design. Reduce/remove acceleration. Adding some sort of HUD / Cockpit / Grounding that does not rotate all the time with the character can help with orientation.
A real world example, i had horrible experiences with ramps at first. Cut them back to no more than 10 - 15 degrees, and made it so the character walks up them a little bit slower and it is heaps better. Still a bit odd, but much better.
So level design is something that should be thought about here too (notice how raw data does not have any ramps? and is mostly flat, yuh, that’d be why)
