Unfortunately, I get motion sickness from pretty much any first person shooter and games where the camera moves around a lot. Timesplitters 2 was the worst for me.

It's gotten a bit worse for me, but a lot of first person games don't bother me. Some that used to not make me sick do now though, so that's weird.

For some reason the demo of some pretentious indie game called The Unfinished Swan hit me hard. I thought I was gonna throw up.

Doom 1 and Doom 2 are the greatest games ever made in my book, and are among the games I've spent the most time with. Even after beating the games multiple times, there's endless replay value with the amount of custom mods and maps that are created by fans.

I've played way more Doom 2 than Doom. Played through the Final Doom map packs more than anything, probably. Those are my favorites to this day.

Still haven't beaten TNT or Plutonia Experiment, those maps are really damn tough. Can't remember how far I've gotten on those, once I'm done with my playthrough of Doom 2 using the Complex Doom mod, I should try and finally beat those.

They're pretty hard, especially the Plutonia Experiment maps. They don't mess around. The two secret maps (31, 32) are straight up nuts.

I've beaten both several times, but I used to play these games constantly, so I was a lot better then than I am now.
