OpenD6 is a tabletop role-playing game system designed for versatility by providing rigid rules where they are needed and loose rules for adoption, rejection, and adaptation. The core game mechanic involves a tiered hierarchy of traits.
This project details a unified Genre System accomplished by close examination of D6 Adventure, D6 Space, and D6 Fantasy. The combination is meant as a guide to creating new game systems in the same way the genre books adapted and built upon the D6 System Book.
