In the eighties and nineties, Roberta and her husband, Ken Williams, were leading figures in the development of graphical adventure games. They founded the company On-Line Systems, which later became Sierra Entertainment.
Williams was instrumental in writing and designing several popular games for Sierra, including the entire King's Quest series, The Colonel's Bequest, Mixed-Up Mother Goose, and Phantasmagoria. Though Sierra was sold in 1996, Williams' production credits date to 1998.
