World of Synnibarr
A high-powered traditional fantasy game set in a hollow world -- actually a generation starship built by a god out of the planet Mars¸ following an eons-long dark ages of plagues and wars. The worldship has both an exterior and interior surface complete with vegetation¸ and is broken up into regions where magic doesn't work and regions where technology doesn't work. The system uses random-roll and class-based character creation. There are 50 character classes including Psielf¸ Bio-Syntha Cyborg¸ Flymen¸ Armored Mantises¸ Amazons¸ Alchemists¸ and more. Advancement is level-based¸ with all classes going up to 600th level. Characters can have ""tenths""¸ where each tenth reduces damage by 1/10 (i.e. two tenths means the character takes 1/100 damage). - A description from https://darkshire.net/jhkim/rpg/encyclopedia/ with kind permission of John H.

This is one of the worst role-playing games ever made.
