I started on Civ (before it was "Civ I") in the early 90s (93?) on a B&W Mac Powerbook 145B
Civ 2 for a LOT of years between a Powerbook 520c and an old lime iMac (one of the original eggshell ones)
Civ 3 once I got a Mac iBook, for about 10 years, including a
lot of time in the office while sitting on 90-minute DoD conference calls where we had about 10 minutes of speaking time and a lot of boredom time (played Civ 3 across 4 different laptops). Beat it on every level of difficulty, and beat it with at least every available civ I had at least once. Easily over 5000 hours, but maybe not quite 10000.
Had IV on a 2 different computers. Hated it. Couldn't stand it. Got about 10-15 hours into it and it never clicked.
Civ V? Yeah, I've
got a
few hours. Certainly over 5000 hours, maybe close to 10000 and not even kidding. Beat it on every level of difficulty at least once, and have every kind of victory multiple times. Played every available civ in the game, won with a lot of them, and added a dozen (or more) add'l civs thru mods and won with most of them, too.
Been playing 6 for over a year now, since I got a laptop powerful enough to run it, and finally getting reasonably competent at it, with a handful of victories of different kinds on different difficulties.
Nubia AAR running now
