i've found that only very detailed or, conversely, low-polygon [umm, what is the plural of fps?] make me nauseus. the detailed ones i think are from the whole realistic movement thing. i can't explain why low polygon ones make me puke though. has anyone here ever played turok 2 for a couple hours, then kneeled over the toilet for half an hour? thankfully, i'm fine with m&b. also, though i can't say i've been an alaskan fisherman, i don't get seasickness either. i think one condition is based on the inner ear, while the other is based on the brain's interpretation of sight. so the two aren't really related
