Out of curiosity, how are you with physical (not virtual) rollercoasters?
In my case- I have done it all. The craziest roller coasters. A sailboat in a storm. I've even done a hammerhead stall in a Cessna. Nothing has ever made me motion sick.
Until I played Half Life 2 in a DK1. After 5 minutes I was so sick I had to lie down. I tried to acclimate myself by doing shorter sessions to build up. Every time resulted in nausea and hours of feeling awful afterwords.
The DK2 arrived. I thought thank god positional tracking must solve it. Not at all. Sick after 5 minutes again. Other things were not so bad. DCS was thrilling, and Elite Dangerous was amazing. Unfortunately, I had the olfactory association with the smell of the glue inside the DK2 with horrible nausea. I could play inside both games for hours, but inevitably the smell would trigger and I had to stop.
With the Vive, I have not been sick in any experience. Because none of them do ground-based translation. Every game I've played uses the teleport paradigm when moving around on a ground plane.
I haven't done the grapple hook based game yet. I hear that one does ground plane translation and makes a lot of people sick.
I did play one demo that was from a game jam where you are floating in an asteroid field. you point the controllers and they act like a jet when you press the trigger. You propel yourself around the space using that method. I didn't get sick at all playing inside that, and I'm almost positive the reason was there was no ground plane involved. My inner ear lizard brain was like "oh, you're just floating around in space not walking... I'm not going to make you sick"
