Yes, I loved Civ I too. Had computers for sixteen years and ignored all of the games. But several different people kept showing me the game, and I got hooked in 1985.
I remember wondering why cities grew so fast near the fish...
Played for years with my son -- I was the development chief and he was the general. "In three turns, I can deliver 2 Armor here, ok?" And he would look at one of my games, "Dad, you've got so many units and they're not DOING anything!"
But, now I play Civ2. The Terrain map of Civ1 was better, showed the roads and such.
I still show Civ1 to my little nephews, one at a time. I tell their parents, It's great practice with math, figuring how many more turns, and they get to read all of that stuff about the wonders and inventions. My little girls played it too -- it's an excellent introduction to history, and military development logistics.
