I've never been a gamer. Except for Descent. And Descent II. I still have them and every few years play them on an old Mac. The queasiness kicks in every time I start playing them again.
Oddly enough I had no problems with Descent / Descent II, but Doom and Doom II wrecked me. I think it may have been because Doom's camera bobbed as you moved to simulate taking steps but Descent's camera was smooth when you moved forward.
