Nintendo even warns about it: http://www.nintendo.com/consumer/man...cn_english.jsp

My brother recently reported not being able to play Quake3 for those same reasons and I dissed him playfully about being such a wuss.

Just this past weekend though, after a couple of hours of Descent3, I started getting nauseous and had to stop playing entirely. This was the first time I'd played this game on my 19" screen in fullscreen mode.

It came as a surprise, but I wonder who else has experienced this?

Any tricks to offset it or delay it?
