I know a number of people who have motion-sickness issues with games like this, it's almost entirely first-person games that cause this.

Some things to consider from my years of assisting managing it:

• You get motion sick because your eyes tell your brain that you're moving, but your inner-ear gyroscopes say you're not, so your brain assumes you must be infected with something so it starts measures to evacuate your stomach of potential poison.

• View bobbing, screen-shaking, depth-of-field, motion-blur and frame-rates have a huge impact on your sense of balance and visual processing of motion, so try to always turn those off. (Minecraft has had view bobbing since early on, it's always "step one" to turn it off for everyone.)

• Framerates also can make you sick. If you're playing an first-person game and the field of view isn't moving smoothly it will be more likely to make you start to feel nauseous. Turn graphics settings down until your frame-rates are at least 40 or so. (You would have to look up the game and/or platform to figure out how to turn on FPS display on your screen to see where you're at.)

• The brain is highly elastic for learning new things, but also learns negative associations. This means sometimes you have to train it like a toddler or puppy. Patiently and with persistence. This can take the form of only playing for 15 minutes instead of waiting until you start to get nauseous. You need to train your brain that the viewing experience isn't actually harmful by disconnecting the association with feeling sick, by getting used to the game without triggering the motion sickness. So frequent, short sessions, not letting yourself get sick. (This is the most effective method anyone I know has tried.)

• Medication. Seriously, anti-histamines work pretty effectively. Motion-sickness pills are literally just anti-allergy medication. It will make you very quite groggy though so don't plan on staying up late playing. Chewable nausea tablets also help a lot. Again, you're just trying to let your brain adapt to a new perspective/activity without getting fully sick, so think of medications as a temporary measure to get to that adaptation point.

• Field of view is also a huge factor. Try turning it up or down, most 3D games give you the option. Additionally, playing on a smaller screen can help a lot too. Play in windowed mode and gradually work on making the screen larger and larger until you've adapted.

• Engagement in the game also helps. Once you start having fun you will often forget about the negative sensations and give your brain more time to adapt. If you're not enjoying a game, don't force it. Try a different one until you find some mechanic you enjoy that hooks you.

• After adaptation, you would likely also need to periodically "refresh" it and play a 3D game for a little while every day or you will slip back into motion-sickness triggers again easily.

I couldn't find conclusive information for Wolfenstein 3D or Doom, but it seems to point toward bobbing being present for those as well.

If it really seems like a game that might be otherwise fun, I'd recommend giving it a shot with bobbing/sway (however it is called) turned of.

This also affects my wife, she has to have it off in order to enjoy any 3d, first person game.
