Ah ok. I'm really hoping my body is immune to all of this. That seriously is such a bummer, getting sick from playing games.I usually get carsick if i'm not driving or in the passenger seat. And i've felt fine with all the other VR games i've tried, though I still haven't gotten through many. No problems there outside of something a pill of meclizine couldn't cure. Ethan Carter is the only game where i've felt actual discomfort compared to just slight veritgo, or wosines which goes away a minute after I take off the headset anyways.
Hell though, your body may be totally fine with it!
Also I think Steam is 2 hours played or two weeks for refund. I could only make it a half hour up to where I explored a house.
