Viper4Dan, thank you very much for this amazing thread. Like Doc, it took me a while to read this as but now I'm hooked by your story and rules. New vistas really opened up for me. I will have a thinking about possible using of the rules for my games.
Any updates on this in the meantime? I perhaps would add some sort of brain test, just for the things like finding or using things, opening chests, interacting with civilians.
