I got cyber sickness the first time I played Quake II. Geez, it was horrible...headache, nausea ect. I didnt feel right for like 2 days

I gave the game away.
It has to do with all that spinning around to view your environment. Flight sims don't work like that, u just pan or snap view in them so they dont make ya sick.
CRASH

If you've never experienced this playing Quake or, most recently in my case, Halflife, let me tell you that it's no fun at all. I've never suffered from it in any flightsim. But I don't know what would happen with a 3D headset on. Something to think about.
