War against the Mongols went slowly, but that conquest was finally completed in 1440. Meanwhile, Willem beat me to Liberalism by three turns and beat me to completing the Taj Mahal by four turns. I delay getting Astronomy after all the AI, because I don't want to give up the bonus from Colossus. Anyway, galleys are enough to reach the Sumerians and start conquering their cities. (I never did get a glimpse of Humbaba, but he must have allowed Willem to become the hero. The Sumerians still hold one captured Dutch city.)
Gandhi had build the Hindu AP and there had been more than one vote for a Religious victory, but Catherine voted for Gandhi, while Roosevelt (the largest Hindu power) voted for himself. I was confident that this even split wasn't a concern for me.
And then came the election of 1625, when Catherine shifts her votes to Roosevelt, who wins a Religious victory with exactly the number of votes needed, 340 of 454! 
In analyzing this defeat, I realized that Gandhi had switched to Free Religion, losing her co-religionist bonus with Catherine, dropping it to only +7, while Roosevelt was at +12. That, apparently, was enough.
So, I submitted my loss (after all, if
we can defeat stronger AI with these alternative victory conditions, turn-about is fair play). But what kind of Ragnarök is this? Ending in peaceful, religious harmony? Besides, my people had already switched to Free Religion and weren't about to pay attention our own tiny (28 votes in the last election) minority of Hindus.
So I continued playing the game for fun. I conquered the Sumerians (Willem finally recaptured his own city, which had shrunk to 1 pop, razing it in the process.) while the Celts conquered the Carthaginians. (Hannibal had been left with one island city at the "official" end.) I decided the Celts, technologically backwards while rivaling my civilization for size, would be my next target. It takes me until 1866 to finish that job, but I capture nearly the whole continent. Roosevelt made a token attack on one Celt city, then settled two of his own cities at the eastern edge of the tundra.
Catherine, Willem, Roosevelt and Gandhi would each be attacked and made vassals, in turn. I founded Sid's Sushi and Mining, Inc., along the way, which accelerated my growing lead. The unofficial Conquest Victory was achieved in 1914, with 7322 points. Even if this hadn't been unofficial, I doubt this would be worth any more than a middle-of-the-pack showing for me. As usual.
Incidentally, the AP votes continued throughout the game, but Catherine never again voted for Roosevelt.
But given distance and so forth, I decided to invade Kublai first, which was shortly before 1AD. Later I landed units on Gilga's land. Dared to do that because, for one reason or another, I couldn't see Humbaba. Even landed a spy to check him out, but he was nowhere to be seen. Gilga did settle a city on Willem's land, which Cathy later captured, so maybe he got lost at sea? Tanks aren't the best swimmers. There were also a pack of galleys in his cities, so it's possible he was stuck in one of them I suppose, though it would be weird to not disembark when I was stealing his cities. Largely by amphibious assaults, granted, but still. Great land he had too, with plenty of food, and some much-needed resources, not least the Gems. And then there was the funky 4
tile...
