I've got to admit, Descent was the only game to ever make me physically ill. Not because it was bad - it really wasn't - but for a short while in the 90s the Genre of "fly tiny spaceship through low resolution, spinning 3D maze where there's constantly a wall right in front of your face" was really popular. Today, I can't watch a five minute gameplay video without feeling nauseous.

I played Descent, Forsaken and Hellbender that all followed that formula. Only later did games like Incoming, G-Police and Yager take the 3D-flyee-shotee genre to the wider outside and it became less nauseating.
