Looks like the update is complete. Perusing now.
Reflavoring: the change of flavor without changing any mechanical part of the game, no matter how small, in order to fit the mechanics to an otherwise unsupported concept. Retexturing: the change of flavor (with at most minor mechanical adaptations) in order to effortlessly create support for a concept without inventing anything new. Houseruling: the change, either minor or major, of the mechanics in order to better reflect a certain aspect of the game, including adapting the rules to fit an otherwise unsupported concept. Homebrewing: the complete invention of something new that fits within the system in order to reflect an unsupported concept. Default module =/= Core mechanic.
