From the Publisher's Website:
Church groups seen as a bunch of holier-than-thou backbiters: can you stay more virtuous and less sinful than the rest? Inspired by requests for an "anti-KPFS".
Task resolution is performed by two parties rolling an opposed number of dice. The player with the highest value die is the winner. Comparing these rolls, any identical values are removed, and then the number of higher value dice is the number of successes.
Characters have two attributes: Virtue and Sin. These are backed by a specifically defined Blessing, Opposed Vice, and Secret Vice.
