I've never had games make me dizzy or give me a headache, guess I'm lucky with that.

For me it would be Descent, too

For me it's :
Half-Life 1
GTA V
Left 4 Dead
and Quake II + III

As far as I remember the very first game I had problems with motion sickness, was Turok. Descent is another game that also does that to me.

Any game that has motion blur makes me feel ill. I have to turn it off or I cannot play.
This is funny because without my glasses everything is in soft focus already, but when I wear my glasses and play everything on screen hurts.

There are two games in my collection I will never finish because of motion problems;
Deus Ex Human Revolution - going in and out of 3rd/1st person gets to me after a few minuets.
Aliens Vs Predator 2000 - Playing the Alien for more then 10 minuets or so give me a headache. The other two are fine though.


EDIT:: spelling

I have no tendency to getting see-sick at all. Same thing for being passenger in cars.
But games can get at me nauseous (how about calling it game-sick).

First time time "a game got me" was at a net cafe some 20 year ago.
Was sitting next to a someone playing quake or something like it, while taking.
Now watching someone else playing without steering the game, was apparently a bad idea.
So i got quite nauseous before I realized it before I stooped watching his screen.

Since then I had no trouble with getting "game-sick" for a long time.
Then at some time I did buy a 24 inch CRT monitor (my last before LCD) and playing my brand new Half Life 2 on it.
That was a new and interesting way to getting "game-sick".
HL2 became notorious for making people game-sick, it was described many places but often people did not know why at that time. Today we know that it is a matter of of field of view.

Here is a precise description of why FOV is so important for game design. And why a to low FOV can gives game sickness. I know that this description is a bit long but is is precise.

So because PC users sit of varying distance to screens of different sizes, any 1st (and a lot of 3rd) persons game should have a FOV slider in their GUI. But some game developers tend to not knowing or ignore this.

Last game I did buy where the missing FOV slider gives me a bit of trouble is The Witcher® 3 - Wild Hunt.

I know now how to deal with it: Move the screen further back on the table and move chair back. increasing the distance from eye to monitor. But it is a lot more fun to to be able to adjust the FOV in the game.

Pretty much any first-person shooter gives me feel sick so avoid them. And recently I've started experiencing problems with third person games too (e.g. Zelda: Twilight Princess). Even games that I've played in the past with no problems I now get sick playing (e.g. GTA: Vice City).

I think it has something to do with the frame rate. Today I play games at steady 60 fps thanks to better hardware but in the past it was like 20-30 fps. I need to test more with frame rate limiter for the games that give me trouble.

Of course the FOV and head bob are probably factors too. Maybe the widescreen versus the old 4:3 screens is making me more sick too. I don't know. It's not something I like to test out.

I think several factors apply FOV is just the most important one for me.

I think that with wider screen and same distance to it the FOV need to be bigger.
Older PC games usually had a FOV at 90 degree. With wide screen displays the FOV need to be bigger in range at 100 to 120. to match the increased Peripheral vision that "hits" the wider screen.

I do think that a games response time need to be fast to avoid that a game makes one sick.
As far as i know the eye can not see more than around 25 frames per second.
But higher frame rates do gives better response time, and this we can feel (I can i think).

Some game make deliberate slow response to emulate the fact that it takes time to change speed in the real world.
HL2 does this so if and i always did disable it via the console can not remember the command any more.

Head boobing also ads to it.

Are you sure it's not just LSD?

Exactly what I was going to say.

Only game that's ever made me physically dizzy.
I can easily see the difference between 30 FPS and 60 FPS, even if it's in a video.

I heard the eye can't detect above 60 FPS, but I don't know for certain. I know people with 120hz monitors can tell the difference between 60 and 120.

Any first-person game that has head-bobbing. The first S.T.A.L.K.E.R. game was particularly bad, with very pronounced side-to-side head-bobbing with the default settings. It had me sick to my stomach in under 5 minutes. Once the head-bobbing was edited out I was able to play for hours at a time without any problems.

While some people are worried about others' questioning a box of Dramamine near their rig, I would rather see that instead of a barf-bucket.

I wonder how many people are going to be able to use the new VR hardware like Oculus Rift without being thrown for a loop.

Wolfenstein made me throw up, and put me off FPS for years. I tried the Minecraft demo a couple of times and ended up having to lie down for half an hour afterwards both times. Usually it is not so bad, but it does mean the game is less fun to play, and I will stop and try something else instead.

DayZ did that for me, but thankfully you can reduce head movements
