dungeons and motion sickness

[Merlinian]

That's not a very nice thing to say... Just wondering, how would you feel if you were that guy that had those circumstances? Or maybe your child or another loved one had what you just listed?

See above. You are basically complaining about something trivial as a video game affecting your health. So quit playing it if it affects your health. Its not like this is a life-essential activity.
If you cannot quit playing despite it affecting your health negatively, you are basically addicted to a video game and have a whole different set of problems.
