Roberta Williams is one of the most well known game authors. She is the
co-founder of the succesful game publisher Sierra On-Line.
Her very first game was Mystery House, a text adventure for the Apple II computer.
It was (according to her) the very first adventure game with computer graphics.
(She did the graphics, by the way). In an old interview, Roberta says that she
get embarrassed when she looks at the graphics now. Other similair games
she wrote were Wizard And The Princess, Mission: Asteroid, the very large Time Zone
and The Dark Crystal.
But then she wrote King's Quest 1 - Quest For The Crown. This became a huge success, so it didn't take too long when Sierra released King's Quest 2 - Romancing The Throne. Currently there are seven KQ games on the market (KQ 3 - To Heir Is Human, KQ4 - The Perils of Rosella, KQ 5 - Absence Makes The Heart Go Yonder!, KQ 6 - Heir Today, Gone Tomorrow and KQ 7 - The Princeless Bride) and the eight one is on the way!
In the manual of The Roberta Williams Anthology (four CDs packed with all her adventure games from Mystery House to full KQ 7 and a playable demo of Phantasmagoria!) Roberta says that she wanted a female heroine just like her previous game, King's Quest 4. She liked the horror night events of that same game, so she wanted to do this again, but this time with another theme. She wanted CB to be one of those murder mystery classics.
And that's EXACTLY what CB (still) is!!
In 1989 Sierra released Colonel's Bequest to the public.
In 1992 Sierra released the second Laura Bow adventure, The Dagger Of Amon Ra. Writing and puzzle designs were handled by Bruce Balfour. It was Roberta's task to make sure that the look-and-feel of this game were the same as Colonel's Bequest. (In my eyes she failed).
(By the way I wrote Roberta Williams an e-mail message (I asked some questions about CB and asking, of course, for a third Laura Bow adventure), but she never replied. It seems that there are no plans for LB3 for now and the future)
