As this is my personal strategy as well, I would like to add that your sample size is now 2, with a 100% success rate :3
Although for me personally I don’t have to retrain that quickly. My resistance to motion sickness certainly gets weaker over time, but I seem to have reached some kind of baseline, compared to my previous state, where about five minutes could give me an awful headache, while now I can take it for a bit longer, even after not being in VR for a month or two.
Speaking of, we need more VR games. I’d love to play more of them, but nothing new is really big and exciting or anything, which is how these long breaks even happen.
