Spaceship launch turn 226, 1580 AD.
Settled on the river hill to get early production and closer access to the hills to the north and west and an immediate 3 food tile. The broad early plan was to settle one city (Shanghai) then go for the Great Library. I built two other settlers and bought one with peace deal gold, settling 5 cities (4 observatory eligible).
Early actions were:
Build order: scout, scout, worker, archer, settler.
Exploration: T3 - 20 culture, T7 - barb camps, T8 - archery, T10 - 20 culture, T12 - scarcher, bronze working
War: T15 Zulu worker steal, T46 Zulu settler steal and peace deal.
I went for a 3 city NC, followed by two additional cities. Shaka attacked Xian right around Education, so right after hitting education I swung down to Construction and Machinery and then wiped him out with Chu-Ko-Nu's. Ulundi was a puppet for a long time before I annexed it late in the game after Plastics.
On Prince I abuse the AI a lot, declaring war and taking luxuries and gold in peace deals. Once this backfired when Alexander took Bogota, so I had to march an army over there to liberate Bogota, razing Sparta in the process.
I had a late entry into Rationalism after taking three policies in Commerce. This slowed down the key Rationalism policies but sped up the founding of Public Schools and Research Labs.
I hit Public Schools turn 159 (using one GS bulb once all Observatories were up +7 turns). Radio turn 166 and Plastics 189. The Rationalism finisher was used for Nanotechnology, and Oxford finished Particle Physics, my last tech. X-Coms helped tribute gold to buy spaceship parts using the Freedom 3rd-tier policy. I bought 3 great scientists and hard-built Hubble in Guangzhou, my best production city with Petra, a factory and a hydro plant.
Late in the game multiple civ's joint DoW'ed me and I ended up wiping out Kamehameha and Alex.
