Shiner

Shiner is primarily this concept, the surrounding story rather slim (although kudos for the ranch dressing-based religion), and it would be lovely to see such a mechanic built into a larger, more established RPG. Of course, this is a student thesis project, and as such is an excellent proof-of-concept for an idea that merits further realisation. Also, it’s free, so if it sounds interesting you’d be a right berk not to check it out.
