I'm 34. I've been playing 'Civ' since 82-83 when a precursor to our wonderful Sid Meier games was available for play at The Evergreen State College in Olympia, WA.
I can't remember all the specifics now, but it was a program that was written in HP basic & brought down from Boeing, where it was written by (bored?) engineers. The game generated islands up to 40x40 or so in a 1000x1000 world - around 10 to 15 bigger islands, lots and lots of mid to small sized ones. Up to 100 players were seeded at the start of the game with one square each & had to build up their civs. Of course, squares were represented by single characters - no fancy graphics here (ok, no graphics at all!). An average game lasted about 3-4 months. You'd get a 'time unit' every two hours. Units were used for production, movement and attack. I remember people waiting for a couple of weeks to launch massive attacks on their neighbors in the wee hours of the morning. Actual fights broke out upon occasion when someone would log in to find that their entire nation had been obliterated by an attack while they had been sleeping! Ahh, the good old days. (I'm sure that now I'd find the game primitive, but reminiscing, it sure seems like it was one of the best games in the history of computers!)
I once had a printout of the source code for the entire game. Minus the actual data files, the source code in HP basic was stacked about 10" high on green bar computer paper. There were more GOTO's than you'd belive possible!

Oh yeah, I should add that I really started gaming a year or two earlier on a mainframe adventure game. I can't remember the name of it (damn memory seems to be running headlong into senility). What I really remember about that game is that most of the mainframe terminals were hardcopy, rather than CRT (that means paper, no monitor for those of you too young to know!), and that a couple hour session produced a truly huge amount of green bar paper! Seems like only a few years ago I went through some stuff stored @ my dad's house & found map printouts on green bar paper. Talk about getting whisked back in time!
