URSWASA - Unnamed Roleplaying System With A Stupid Acronym
The premise of the game is simple: a huge¸ Rome-like empire (the Numae) conquer the galaxy¸ only to be toppled by alien invaders (the Demons). Eventually¸ the fragmented survivors form societies roughly equivalent to Medieval Europe¸ with a dominant religion and a few bits of out-of-place weirdness added in.URSWASA is short for Unnamed Roleplaying System With A Stupid Acronym¸ a rules system designed by Michael Collins to be relatively useful and mathematically elegant.
