Williams was a financial planner who saw the potential for transforming the debt-plagued company into a highly profitable one. However, she disdained the gaming field, viewing herself as superior to gamers.[5][6] Williams implemented an internal policy under which playing games was forbidden at the company. This resulted in many products being released without being playtested (some were playtested "on the sly") and a large number of products being released that were incompatible with the existing game system.
