I had 30 min in a certified helicopter simulator earlier this year. The sim was built out of an actual fuselage (Sikorsky S-76) with full controls, visuals were 8x projectors on a curved wall in front of and around the cockpit. Everything was bolted to the floor, no movement anywhere. After 10-15 minutes I did a hard bank and my gosh, the whole world moved, and I could have sworn I was about to slide out of my seat. I panicked that I didn't have a harness on. The instructor laughed and said that was quite normal and that many people get very motion sick. So yeah, I can see that motion sickness, with the "right" setup, could easily be a thing.
