The idea that a moving 2D image is capable of resulting in motion sickness because the scrunched up viewfield implies to our brain different movement than we are used to in a game is not something those who are set against the idea will readily accept. It requires a bit more acceptance that the brain infers more 3D from 2D images and the processes behind motion sickness than most people tend to consider or even think about.
it CAN happen i NEVER get motion sick but i did this last summer coming back from Anime Expo
was watching Macross Plus on the plane back and we hit some rough air
right when i was watching a dog fight in anime BAD THING nearly go sick all over the laptop >.<
whats happening is your brain is getting 3 different queues
your ear is telling you in my case im moving one way
my focused vision is saying some thing else and my side vision says im not moving in relation to things around me
you dont think about it but your mind is taking in a lot of info from your peripheral vision and thats whats happing here some people are more or less senseative to it
