I guess if you dogfight and get into circle strafing, that could be bad. But, if you do that in Elite, you'll die before you get motion sickness.
Eve: Valkyrie makes me sick, I'm working up my tolerance. But there's no refined flight mechanic, there's not even throttle just boost and brake. That leads to circle strafing enemies, flying through buildings, and madly looking around where the guy is that's shooting you. That's how one gets sick.
