Maybe he meant motion sickness? Some people get motion sickness in some FPS (I know because I sometimes do ). And some are more susceptible than others. Endless Ocean is first person (albeit not a shooter), so I guess some people may get motion sickness from the game (?)
It has a 1st person option, but the default is 3rd person. So I still don't get it.
Ah, I was under the impression it was FP only. So I now join the ranks of the "I don't get why his wife got seasick"... Maybe it was a joke, and he just meant she didn't like it (so she was "sea sick").
