I don't remember exactly... I played King's Quest I for the first time about 25 years ago
I was 8 or 9 years old, and I think I played it for the first time on the office PC of my father's friend. My first memories of KQI are about repeatedly falling into the moat
Then we got an 8088 with CGA at home, later upgraded with a hard disk and a VGA card. I played most early Sierra adventures on that PC.
Other assorted fond memories:
- The first Sierra game I completed was KQII
- Later I also completed KQI, and I had to do it in a single session because for some reason I couldn't get the savegames to work.
- I played Leisure Suit Larry I when I was 11 or 12, and I remember asking my babysitter: "What is a condom?". She explained it to me, but her answer didn't make much sense to me at the time yet
