I learned on a Macintosh in 1988, when I was manager of a student union.
There wasn't much to it, but man, I miss it.
There was some sort of game called "Strategic Conquest," and I played that for hours, for days, at a time. I was young yet, and easily obsessed.
I mean to say I used to play it for hours, for days, at a time.
Whenever I would go live in houses of wealthy people while they were on long vacations (cheaper to pay me to be there, than to board the pets), I would hole up and play that game nonstop.
It perhaps wasn't healthy, but ultimately I outgrew it, about the time I took off for the socialist paradises of the workers and peasants.
I've seen post-1988 versions of Strategic Conquest, but they aren't nothing, compared with that ancient version.
