I got Education with the help of a natural GS in turn 312. That was one turn after conquering the last capital on the home continent (Paris). That same turn, I bought a university in Berlin. 3 turns later, when I had enough money, I got another university in Hamburg. Which was my only expo.
Well planned getting the GS before the free GE increased the cost! Didn't not annexing weigh down on your happiness? I used double citadels to connect truffles near Amsterdam, built courthouses, colosseums, etc., and still barely kept happiness above zero.
Turn 376 win here.
Most of the actual playing time was spent roaming with lone military units, looking for new camps, and chopping forests. Camps were necessary to avoid deficit, which I managed to do until the very turn I learned Astronomy. I then had deficit for two turns more before I saw the problem - the game seems to have become much stricter about disbanding military, which used to be an empty threat - sold off an aqueduct, etc.
Camp yields
brute: 10
archer: 8
spear: 7
sword: 3
horse: 5
cb: 1
pike: 2
axe: 8
Seventy-five Gold: 31 (41%)
Total Military: 44 (59%) I thought the figures would be closer to 33%-67% but they were not abnormal.
Some Key dates after turn 197
218 - Paris puppeted. But has library.
221 - Vienna puppeted. I eventually annexed all the home continent capitals except Rio, which didn't have any forests to boost a Courthouse build. London (Pyramids, Writers' Guild) and Beijing (Parthenon, Petra, Artemis) were mildly useful. (Berlin eventually had 6 great wonders.)
t234 Liberty tree complete. 20 turn golden age. Free GE, hurried National College (34 turns, 1075 hammers. Science goes from 54 to 69.
235 3rd great general. He will converge with the army near Brazil while his brethren build citadels to reach some truffles.
239 Unmet player lost capital. I was never to meet them.
266 - Enhance religion. Choosing between Pagodas and Swords into plowshares, I chose Pagodas. Sure, there would be some peace time to grow before we meet the other civ(s) but happiness seemed a bigger issue. Not sure that was right, because I only got 3 pagodas and spent 51 turns in peace before astronomy. I also picked Holy Order, cheaper missionaries.
267 - Built Great Wall! I didn't want a far away land to get it. This was apparently the only wonder I had never built before, because I got this Steam award:
297 - The last home continent civ, Greece, is eliminated.
348 - Astronomy. I wanted to press on to Navigation, but it was grotesquely expensive and turned out to be ultimately useless too. Like for The Black Vegetable it took time to find the last civs. I found the barb-infested island pretty fast with some stray units, but they could not survive. The mini-map shows quite a few tracks in the water(!).
My dream for a marathon Germany game is to somehow get a hand axe upgraded to a knight thousands of years early
I had one shot at that on the barbarian island, but got 60 culture instead. I also had a shot with a horseman but got population increase. That wasn't super early either, obviously.
363 - Met Mongolia.
370 - Captured Rome, which was governed by the Mongols.
376 - Captured Karakorum.
Edit: I kept two Greek expos, one because of 2 luxes and the other one because of Great Lighthouse.
