Experiences getting sick when playing games

I remember thinking about this when I got my PS2 my headaches disappeared altogether. I think it was the jaggies giving me headaches. I got the worst headaches playing Driver 2 and that game was considered graphically advanced! It had to be the jaggies...

I hate to play Castle Wolfenstein in this regard. The whole game environment doesn't suit me best and it's a very sickly feeling that I get while playing this game. It was a long time back and I don't want to play the game again. Another game was QuakeIII. I was addicted to it like hell and all the fast movements and sounds and a not-so-great color ambiance of the game made me quit it at last. I play Counter-Strike 1.6 and Dota now. Both are pretty decent and doesn't put a lot of pressure on your mind while playing. I love both of them and I can easily play them for hours without getting bored or tired or sick, whatever!

A few years back, I really got addicted to online games. Specifically, Ragnarok Online. One time, I even had the routine of sleep, play, eat, smoke, play, eat, play, smoke, play, sleep. I'm not accurate but that's pretty much the gist. I just felt so tired and even felt that I'll get a fever. And I got more, I got weak after getting addicted to it for almost 1 month. Good thing, I woke up and went back to reality and start living outside the online game world.
