Asylum
A horror game set 150 years in the future where everyone is insane after an biological disaster that darkened the skies with mutant spores. The majority of the world's population lives in Wards: city-sized secure areas where the population of inmates is fed¸ watched¸ and treated by the Warden. The mechanics are a simple skill-based system¸ which uses colored marbles instead of dice: draw out two marbles from a bag of 10 (2 each of 5 colors). The colors map onto numbers 1-5¸ but for various charts the individual colors matter. It uses point-based character generation. - A description from https://darkshire.net/jhkim/rpg/encyclopedia/ with kind permission of John H. Kim
