The “Tuscany Villa” is an ancient demo that I tried in the Oculus DK1 in like 2014 or so, and it made me sick for hours. It uses very fast continuous movement instead of teleport, and it has a set of stairs that will make you instantly throw up if you try to climb them.
It’s is perfectly possible to create VR experiences that will not make anyone nauseous, Moss being a good example.
