My army at the end consisted of 35 warriors, 3 chariots and 1 airship.
That was highly efficient!
I also got a Diplo win, 1949, with somewhat more units.
Actually, I got Domination the same turn, but the RNG came up Diplo. This was a real nail-biter for me, contending with Cultural attempts by Hattie and Pacal. They each got within 10 turns, as I frantically sent spies to their 3rd-to-be-Legendary cities to cause revolts.
At 1AD I had 6 cities and 25 pop. Got the Great Lib 250 AD, then Music/Great Artist 375, Parthenon in 475, and bulbed Philo for Taoism 620. I ran Pacifism to spam Scientists and did a triple bulb for Optics + Astro in 1200 and met Shaka shortly after. Hmm... why do I not have any foreign trade routes after all my efforts to get Astro?!
Ah, Shaka has no coastal city that I can reach! Fortunately there was a sliver of land he hadn't settled so I shipped over a settler and grabbed it. He and Ragnar were at war, though, so I didn't have as many trade connections as I'd hoped--the route to Hattie fixed that soon after, though. My plan was to ship units to Ragnar's side of the border, attack and vassalize Shaka, and then turn on Ragnar. But before I could do that, Ragnar beat up Shaka and vassalized him!
I hadn't planned on fighting both of them at once, but whatcha gonna do? I was first to Steel (and had a monopoly for quite awhile) so once I got enough cannon I finally attacked in 1700. By 1864 Shaka was dead after a rather tense war and I could turn all my attention to Ragnar, who now had cannon, too. I also noticed at that time that Pacal was going for Culture and was 51 turns away.
In 1919 I finally vassalized Ragnar after beating him down to 1 city (so that I could get access to his east coast and thus to Pacal), getting MilSci, Democ, and Divine Right. I was still behind the other AIs by several techs but still had a monopoly (apart from Rags) on Artillery. Meanwhile, my spies had been causing mischief in Pacal's 3rd cultural city and he eventually gave up and switched to Space. Phew! But now Hattie was even closer to a Culture win (about 15 turns to go) so I turned to her and noticed she had 53 destroyers and 5 battleships in Thebes!
(OK, not as good as the 100 ships you saw, WelshG, but I was pretty amused--I stopped smiling once my airships revealed some of her subs.) I shipped over lots of my Zulu/Viking veterans and DoW'd her around 1932, taking Thebes (one of her Legendary cities) in 1940. I'd also shipped over some units from Norseland by ship to Maya and taken one of her southeastern cities. That was enough to get her to capitulate! Oh, Stalin had DoW'd me during the Ragnar war and taken my beach head city on Egypt's western coast, but once I took that back (to get at Hattie) he capitulated to me.
After Hattie was neutralized, Pacal was again the main threat, about 10 turns away from a Culture win. With all my veteran units now streaming toward him from 2 directions he fell pretty quickly and I vassalized him in 1947. I was right on the edge of the Dom land requirement and not entirely sure I'd be able to meet it, so when the UN vote screen came up next turn I chose the Victory vote, since I was sure I could win that. As it turned out, I got 64.14% land next turn when some captured cities popped their borders. I'd pretty well caught up in tech with everybody but Mehmed by the end--he was working on Space but quite far off from launch.
This was a real fun one!
I did make some real dumb mistakes, though. Should have sent the warrior to the west (instead of SW onto the hill) so I could see more of the SIP position--wasted 2 turns wandering before coming back to the original location. I also had a brain fart and did a 2-turn revolt BEFORE starting my first Golden Age with the Music Artist that I'd specifically been saving for the occasion. And then I sold my map to Pacal 2 turns before I would have gotten circumnav.
I also didn't get Moai and Oxford until.... well,
really late.
