As someone who got motion sickness playing Doom (and yet still played it to death) I
can relate to those who feel sick playing Half-Life 2. Various places
on the net have reports of a sizeable chunk of people suffering nausea and other symptoms from playing Valve's latest
brainchild.
Video games have, for many years, carried warnings about epilepsy and seizure. Is it about time for a "May cause
motion sickness or nausea" label?
Just to be different, link goes to Google Groups archive of a newsgroup discussion. Other folk suffering from nausea
can be found
here.
