I think part of the problem is related to anticipating the motion. That would explain why a lot of people have problems watching other people play, but not playing themselves. Basically like when you're driving a car with a manual transmission, you can anticipate the gears shifting but the others in the car lurch forward and back.

There are a few games which stuttered badly during play and those bothered me - again, because I couldn't anticipate what I was going to be seeing. It's like walking around drunk.

My wife gets ill from some 3D games. Particularly FPS games. She can't even watch me play Gears of War on the projector - the shaky camera thing combined with the 3D makes her feel icky.

I got her Buffy for the original xbox and it made her vomit within about 5 minutes. It's pretty rare she has a reaction like that. Oddly games like Mario Kart she's OK with. She also does better if she's playing - she says it is worse watching.

She also gets motion sick, though. She took dramamine when we traveled through the mountains during our wedding/honeymoon trip.

I got very sick the first time I play Timesplitters 2 for some reason. I ended up puking the whole night. No other game has had that effect on me though, including the first Timesplitters. Even hundreds of hours of Morrowind and its blocky graphics didn't do anything.

I get sick from playing Ridge Racer 6 but it had nothing to do with the game being 3D.

I felt a little nauseous playing Superman Returns and Spider-Man 3. I think that has to do with the fact that there are times in the game where I can't tell which way is up (Spidey crawling on buildings, Superman flying fast in different directions.)

I remember Golden Eye for N64 would make me feel like this. I would lay in bed for about an hour before I felt better, then I would go back to playing. It still happens sometimes with certain games on the 360.

How can you see anything at all from that distance?

I play my 360 on my 19" monitor and I sit about 1 foot from it.

I never get motion sickness. There has only been one game that made me even slightly dizzy: Prey. The gravity puzzles in that game that flip the room upside down and every which way is trippy.
