Hey! I tried this out. I didn't really get motion sick, but then again, I sorta did because the horizon changes instead of just changing the boat. I got used to it. The graphics are alright, but nicest I've seen in a sailing game.
It would be nice to hear the wind running over my ears so I can judge it's direction.
(and ya know, make everything look awesome, and have a wind + cloth sim on the sail)
