This is correct.
I get sick from some shooter but not from others, games from Valve usually make me sick because Valve likes to use a wider FOV in their games. So you would see more of the peripheral vision. Half-Life 1 made me sick, as did HL2 and the Episodes. I also had the issue with CS:Source. I forced myself through HL2, I threw up at least twice but after I got through halfway I was more or less okay for periods of over two hours.
When a game makes me sick, (I started FarCry about two months ago and I am only 2 hours in.) I will usually have to play for some time until I am accusomted to it. And it is not always the FOV that is the problem, is it also the move ment of the camera. The 'bobbing' effect you get when you move, that combined with a strange FOV messes me up.
Ever since I got a widescreen monitor it has been worse. The monitor being widescreen was an unforseen negative as the games will sometimes change the FOV to fit the monitor as opposed to streching the view. This was the case with Bioshock and that took me the first 3 hours to get used to.
As I play more and more games it really becomes less of a problem then it used to be. But there are still some games that are almost unplayable. HL2 used to be that game for me but now it is Farcry and Painkiller. Those two will still mess me up good if I play them for more than 10 minutes.
I will make a list too, of games that make or made me sick. The more plusses the sicker.

Some of these games I am now fine with, others will me make nasueous for hours.
So yeah, there are those of us who suffer. There sure aren't a lot of us though. When HL2 made me sick I spent a couple of hours searching online for "HL2 Headache fix" and the like. And I found just one forum on which some guy suggest changin the FOV. Which worked but by that time I was getting sick just looking at the title menu, I was conditioned to feel sick in way. Took a while until it was okay.
Man, I am interesting.
