Why do I get sick when I'm lost (in a game)? [duplicate]
Solution 1:
I've experienced this and in my case I believe it's because when I'm lost I'll start to run around the map (using the run function if there is one) looking for something familiar or some enemy I haven't killed.
All this running means a lot of turning around and thus a lot of visual input. The result is a motion-sickness like feeling.
Your mileage may vary.
