In 1999 Pyramid magazine named Margaret Weis as one of The Millennium's Most Influential Persons "at least in the realm of adventure gaming." The magazine stated that Tracy Hickman and Margaret Weis are "basically responsible for the entire gaming fiction genre." Weis was inducted into the Origins Hall of Fame in 2002, recognized in part for "one game line turned literary sensation: Dragonlance."
In addition to her writing career, Margaret serves as the owner and chief officer of two publishing companies, including Sovereign Press, Inc., a game publisher based in Lake Geneva, Wisconsin. The company used to own the license to Larry Elmore's Sovereign Stone RPG world, hence the name of the company. It now produces the Dragonlance line of game products, licensed from Wizards of the Coast. Her newest company, Margaret Weis Productions, Ltd, publishes RPG line based on several licenses including Serenity and Battlestar Galactica as well as Ed Greenwood's new solo venture into roleplaying, Castlemourn.
