Space in 1715AD
The game started off quite well by getting both Bronze Working (3800AD) and Writing (3240BBC) from huts
taking care to always pop them through culture or Scouts
Then the big question was how soon I needed Astronomy for the additional cities. Since I could already settle 10 cities on my continent I decided that getting decent research through Bureaucracy + Oxford (in the northern city near the Banana) was a bigger priority so I went towards Education.
I placed my fourth or fifth city correctly and soon became aware of Ragnar. Now some EVIL person had put his starting Settler on a tiny island which completely crippled his development. In the early ADs, he had four cities and not even Monarchy! I shed a tear upon seeing this, and since he didn't even have Iron/Bronze hooked up I whipped the most pathetic attack force the ADs have ever seen: 4 Swords + 4 Catapults. But instead of being laughed off the continent it managed to take all three of his mainland cities
and upon getting Astronomy it also took his island capital.
While expanding, I built the necessary wonders rather late, whenever I needed them - Mausoleum, Great Lighthouse, Oracle (for Civil Service), Hanging Gardens. Didn't build Pyramids without Stone as Constitution wasn't that far away by that time, and Collossus would have been obsoleted too early. I also beelined Communism after Astronomy as maintenance was getting too high and I couldn't create an Engineer for Mining Inc. anyway so State Property it was until the end.
I met Charlemagne, and again not wanting to take too much away from infrastructure + research I had a few cities only contribute a couple of Maces + Trebs each for him. Again to my surprise, this tiny force managed to take five of his cities quick by being ferried around with Galleons
! After that I couldn't advance well with so few units, but when the Trebs magically turned into Cannons and the CR3 Maces into Infantry (skipping the whole Renaissance) it became easier
.
And since I had already paid the cost for the upgrade and there were still some Infantry left, I shipped them over to Stalin. Now that was a sad chapter...his island capital was defended by three Longbows but two of them were camping on a tile besides the capital! So one amphibious attack later the capital was mine and they suicided against the city. His second city was defended by a single Warrior (keep in mind this is about 1000AD, not 3000BC).
I stopped attacking anyone after taking three cities from Stalin. Nobody else ever attacked anyone so it was a rather peaceful game, and I went through the motions of building spaceship parts.
Maximum beakers/turn: 4500
Cities at 1AD: 10
Cities in the end: 34
