I didn't know the name, for any others like myself:
Roberta Lynn Williams (née Heuer; born February 16, 1953) is an American video game designer and writer, who co-founded Sierra On-Line with her husband, game developer Ken Williams.
In 1980, her first game, Mystery House, became a modest commercial success; it is credited as the first graphic adventure game.
She is also known for creating and maintaining the King's Quest series, as well as designing the full motion video game Phantasmagoria in 1995.
The Digital Antiquarian has a good article about Roberta Williams:
40 years of the Rumpelstiltskin puzzle (that also depends on a misspelling of the character as Rumplestiltskin). Thankfully, that puzzle was optional at least, unless you wanted to full score.
I can't say that I love or even like any of the King's Quest games, but it's undeniable how important they were for an entire industry, so cheers to that!
I have such great memories playing all the Sierra games back in the 80s on my IBM PC, overcoming all that difficulty over weeks and weeks of trying to figure out what to type to get to the next stage of the game. No internet, giving us all that space to imagine and wonder what those world may be like, imagination going off with the help of all the constraints of EGA/VGA graphics, that was a special time. Roberta and Kenneth, all my respects.
