Some of the older games on pc especially deus ex makes me extremely nauseous. 10 minutes is all I can handle before feeling as if I am going to pass out and that is after whatever tweaking I did. Never had the problem when I was still a kid but I played on a crt monitor. I don’t really get motion sickness unless I try to read books on a bus and it doesn’t even happen on a train but some games like deus ex are just unplayable because of this.
