At that time I was really bad at English (==learning a foreign language at school is inefficient anyway).
Then King's Quest 3 arrived on my father's Mac SE.
What a blast! With my tiny french/english dictionary, I worked superhard to understand the texts, and input commands correctly. And with the help of Minitel forums (the french Usenet, accessible from any Minitel that every french family had at home at that time), I eventually finished the game. My English level skyrocketed.
And it was the beginning of my love story with Sierra games.
King's Quest III was amazing; when I went off to college I upgraded to a Quadra 840AV which allowed me to play the first three games (as well as the Space Quest & Monkey Island series) in color.
It was like the Wizard of Oz shifting into color for the first time… just amazing.
Switched to a PC for a similar experience :)
When King's Quest 5 was released, you needed a 386 and a vga card.
Shit, that was much beyond what I would ever have access to.
(and then came the Moore's Law).
The Pirates of Pestulon? I like it, though perhaps it was the more "gimmicky" of the first three. They are my favorite Sierra adventures, in their unadulterated low-res, text-based, 16-color pixelated glory. Vohaul's Revenge is my favorite, perhaps because it was my first.
The VGA point-and-click remakes did a great disservice to these fantastic games.
Oh, the dithering!!
