Thanks for the warning, I cannot even play Minecraft. I wish Carmack had tackled motion sickness in VR/Games before switching to AI; he did talk about it in the interviews as being a limitation though.
There's a need gap[1] to solve Simulation Sickness in VR and First Person games.
I was under the impression that simulation sickness was largely solved outside of extreme cases (like a vr portal game). I thought we're just waiting for hardware to catch up.
Years ago John said if you have 20k and a dedicated room you can make a convincing vr experience that won't make anyone sick.
I loved and finished the game but I had the same issue on two occasions. I felt sick and I had to stop. Now I know it was not the food I had just eaten but the game itself, thank you!
