Round 15: to 1938 AD
In a way, the real competition a Civ player has when you're in a commanding position in the end game is against yourself. The AI is rarely in a position to challenge you, and often does not. So you're really just trying to finish as quickly as possible, and maybe milk your score, to see how you fare in your personal hall of fame.
To that end, I founded a few cities in the end game, starting with this one:
What's funny is we talked about founding this city very early on, and I just managed to get to it now, when the game's almost done!

It actually grew to a decent size by the end, about 9 pop IIRC, helped immeasurably by that wheat tile. The goal of this and the two additional cities I founded late was to grow my population to max out the end-game score. In retrospect, I should have founded the last two cities much earlier (one of 'em never made it past 1 pop), but I had other things on my mind.
Such as the space race! I was mindful of aelf chiding me about my use of the earlier Great Engineer for the Three Gorges Dam when I coulda and shoulda saved him for the Space Elevator. A good point, and one I'll remember in the future. My next great person came out of Tokyo:
That was a little surprising--I was expecting a Great Prophet, based upon the numbers--but not disappointing. My plan was to save this GP, whichever type he turned out to be, for a possible golden age to pump up my space race research and production.
Before I got my next GP, however, I had to finish up the conflict with Ragnar. My amphibious force had to sail all the way from the southern shores of the continent to the north, so it took some time, but the Marines eventually had their say:
...and Ragnar was no more. I kept both cities, what the heck--more pop for score milking, and no opportunity for the AI to set up shop in my northern back yard.
Those final attacks earned me my next (and last) Great General, mainly because I used ships to remove the defensive bonus of those last two cities, but I made minimal use of Artillery and none of Bombers to weaken the defenders. So the Marines were usually facing 80% odds, good enough to win (which I think they all did) while earning plenty of XPs. I sent the GG to Madras:
I used him for a military academy. Earlier, just before and during the war with Ragnar, I had wanted to make Madras my second military city. But it was experiencing mounting unhappiness and health issues and needed several civilian builds to keep it productive. As a result, the capital, Delhi, wound up filling that role of 2nd military city, with a military academy and an instructor. It turned out okay, but since Delhi was also my main science (Oxford)
and commerce (shrine + Wall Street) city, it probably wasn't optimal. At the time, however, Delhi had the infrastructure to stay happy and healthy while churning out units at a decent rate, and so it got the nod. I eventually built the Red Cross in Madras as well, and it became devoted to churning out my deterrent force of ships and, later, Mechanized Infantry.
With the war against Ragnar over, it was time to change civics for the last time in the game:
All designed to max out production and research, as well as take advantage of the many wonders I had captured such as the Kremlin. I didn't really cottage spam as much as Cabert recommended. I had a few cities with riverside tiles, and they would produce as much gold as a hamlet in the same spot immediately, as well as boosting production for space ship parts, so I tended to go that route. As cities ran out of needed or helpful builds, I began to build Wealth in order to boost the research slider, which climbed from 80% to 90% to 100% for the last few turns.
As far as research goes, it may not have been optimal for the space race either. My choices were complicated by the fact that I had captured
all three wonders that would be made obsolete by Computers! (U. of Sankore, Spiral Minaret, and Angkor Wat) I usually don't hesitate to acquire a tech that obsoletes a wonder, but
dang, three of 'em? Eventually, though, I realized that it was high time. In fact, I should have (and usually do) bee-line to Computers first, so I can get those Laboratories in place for their research and space ship part building bonus. As it was, the route I took was Satellites -> Computers -> Fiber Optics -> Robotics -> Fusion -> Refrigeration -> Genetics -> Ecology. Looking back, I probably should have gotten Computers first, then Satellites and Robotics to get going on the Space Elevator a little earlier.
Fortunately, despite my slightly-less-than-optimal tech path, I was extremely lucky with my Great People. The next one appeared in Patak:
YES!! A Great Engineer to help with the Space Elevator, which I decided to build in Bursa (Kyoto and Satsuma were busy with other space ship parts, Bangalore and Madras with military). Now I needed another Great Person for a golden age. The next one would appear in my GP Farm, Lahore:
Uh-oh. The leading candidate there was a Great Artist, thanks to all those GA wonders. Two Great Artists do not a Golden Age make; you need two
different kinds of Great People. I wished I'd obtained that Great Prophet from Kyoto. I kept my fingers crossed that the game would continue to be perverse and
not give me the top-rated GP. If worse came to worst and I had two Great Artists, I'd use the Great Engineer from Fusion to start the Golden Age.
My luck held:
Can you believe that?
Another Great Engineer--and one turn before I'd get a third one! I started the Golden Age immediately. On the next turn...
This GE I sent to Bursa to finish the Space Elevator.
Yeah, it only had 3 turns to go, but I had several space ship parts under way, and a saved turn is grist for the mill in the adjusted final score.
A few turns later, in 1935, I had all my techs in place and only three parts left to complete. Production powerhouse Kyoto would finish the Engine in 1 turn, while Satsuma had 3 turns to go for the Stasis Chamber, and former Viking city Sigtuna (which I'd transformed into a production city by replacing its farms with waterwheels and workshops) had as many to go for the Life Support:
So it was really just a matter of playing out the last three turns, during which I micromanaged my cities, putting specialists back to work on food-rich tiles to max out my population. In 1938...
I hate to rub it in, but the victory was just a little sweeter this time because some of you thought the game was lost in the early rounds.

But I can't get too cocky, because the same community told me what I had to do to perform the course correction that pulled India's economy out of the doldrums. But we can discuss that in more detail in the post mortem, which is next.
