20K win in 1640AD.
It was just too easy - even Warlords in GOTM78 put up more of a fight.
The main difficulty was getting the troops in place, but that became very simple after Cavalry and RR.
Main events:
70BC - 1st Leader in war with Celts we were fighting since 400BC. We were 8 turns till GLH, 1turn till Monotheism, and so desided to spare it until nice MA wonder.
We learned Monarchy next turn from GL, and switched to HG, which we finished in:
90AD - entering the Golden Age. As we had Theology by then we hurried Sistine Chapel next turn.
AIs were pretty much useless research-wise, they couldn't even get me Invention, so I was forced to self-research Music Theory and the lower path up till IA.
AIs gave me Chivalry, and Babs in IA were kind enough to do Navigation and Economics. And that was it from AIs till the end of the game, apart from free techs.
But our own research rate stayed at 4-5 turns right after the end of GA and till the end of the game.
RNG was kind to us and we got couple of easy GLs in Middle Ages. We were pretty methodical in destroying Celts, destroying Germany except 1 tundra city, warring with everyone settling on our "half" of the continent and in the end destroying everyone but Babs, (and leaving Persia and Germany with 1 city).
Babs we nurtured so that they would create a decent empire and enough units for us to bash later in the Modern Age.
We didn't bother exploring the seas until we got Magnetism, as it was unlikely English would have anything to offer.
After we discovered English (~750AD) we didn't trade their contact to anyone - and all the rest of the Civs were still far away from Magnetism or even Astronomy when we razed British Empire off the map, taking only Spice cities. I think we got 1GL in the process.
~600AD - we researched MT ourselves, as it took too long to move the troops around.
740AD - we went Industrial.
900AD - We learned RR and Industry and maxed out Paris with new technologies.
After that we took a break from industrial research and went for Free Artistry etc. I thought we'd have to research Economics and Nav., but as I mentioned Babs unexpectedly helped us there.
1180AD - England gone.
1270AD - FP hand-built in Hanover, at about 5-6spt amidst celebrations.
1390AD - we became Modern. Gifted city-states Persia and Germany, Germany got Computers which I bought from them for huge gpt. Persia got Ecology which I traded for Computers and more gpt. Babs I didn't gift as I was going to be fighting them till the end of the game, and I wanted them backwards. And I got Computers anyway already.
Next turn we dowed both Germany and Persia, of course.

And finally erased them off the map. So it was us against Babs till the end. Nothing personal, just wanted some GLs.

And we got them aplenty, every turn or two, hurrying all the Modern Wonders.
1480AD: Babs are one city. All Great Wonders built. Hand-finishing Apollo and some rag-tag Wonders. Pressing Enter till the end of the game.
