I'm not a big gamer, but I once tried a WW2 game where I was a soldier who walked around finding things and shooting Germans (first person game?). After about an hour of looking up and around made me feel sick for a couple of hours after. I like flight sims and don't have the same problem with them.
I went to a bowling place once, and they had an arcade shooting game, and you have to put the giant goggles on to see the screen, and I was smacked in the head with a pool cue by a mate when I had my head inside these goggles.
I got over excited once fell of my chair and sprained my wrist playing dod sorce once, the only thing was it was my mouse hand (right) coulden`t play for at least a week that was a bummer well to me it was.
