The adventure game market wasn't quite so male-dominated, especially where Sierra was concerned, with a large number of female game designers, and multiple influential games with well-developed female protagonists 1-2 years before even the original Monkey Island came out.
Thanks, didn’t know. I knew about Roberta Williams, but I did not play the Sierra games much (that I remember, only Kings Quest 3, which was the first adventure game I ever played).
