Jamie Chambers wrote short stories which added to the Sovereign Stone world mythos, and also ran the Sovereign Stone website. Margaret Weis and Don Perrin, with Chambers and Christopher Coyle, authored the Dragonlance Campaign Setting (2003) through the d20 license with by Wizards of the Coast who published the book, with the license also allowing Sovereign Press to continue to expand and supplement that book. Chambers designed Serenity Role Playing Game (2005) using the Cortex System, the first release from Margaret Weis Productions. Through Margaret Weis Productions, Chambers also created and published the role playing games Battlestar Galactica and Supernatural. At the time, Serenity RPG was the most popular role playing game since the original Dungeons and Dragons, requiring four print runs in the first year of publishing.

Chambers created the Cortex System for the Serenity Role Playing Game during his time at Margaret Weis Productions. He then used it for additional licensed game supplements, several of which were based on television shows and movies, including Battlestar Galactica and Supernatural. The Cortex System shifted away from gameplay determined by the rules toward a gaming experience guided by them, which was considered a necessary step to counterbalance the computerization of role playing games. The system allows the game to evolve throughout a game session, providing the players with ways to create and modify the rules to meet their needs. The system was later adapted into Cortex Plus and Cortex "Prime" by Cam Banks when he took over for Chambers at Margaret Weis Productions as lead designer. Banks later founded Magic Vacuum, a production studio that has licensed the original Cortex System and the revised Cortex Plus, which is considered more narrative than the original Cortex system, building on the move away from systems constrained by rules and allowing further differentiation from computerized role playing games.
