After seeing Toku, I sent a WB exploring to see if there were any nearby islands. The peninsula in the north was perfect, so I decided to go with an espionage game as soon as spotted that. I figured that I would only need the following: COL (for Caste for Artists), Alphabet (for spies), Sailing (to settle a city on that peninsula), 3 GA, a pile of spies, and maybe, time-permitting, a GSpy. Peter obliged by teching Alphabet very early, so I didn't even need that, but I realized that I would need to finish Currency. Aside from all that, I had to beat down Toku, give him a city on the north continent, have him spawn Korea, kill Toku, move Korea off-continent.
Beating down Toku involved only chariots. I would capture a worker, capture a city, then CF, rinse and repeat. His refusal to talk with these wars is quite something! After taking his 3 original cities, I had to give him a couple of mine to keep him alive, while I settle the off-continent city. One of them was a Confu-holy-city future LC. Allowing him to accumulate culture there created a real nuisance later on.
Things I did wrong:
- Horrific

to

conversion rate... I probably averaged about 1.7-1.8x. The biggest thing missing was the stationary bonus, but there are probably other issues that I still need to figure out.
- With zero espionage-victory experience, I seriously underestimated the effort in building up an army of spies. I stayed in Caste for a long time trying to get my 100% GA's. Getting a cheap GP for a golden age and running everything off in 8t+ would have been better, I'm sure. As it is, I couldn't be in Slavery much at the time when I really needed production.
- I also under-expanded. The entire eastern part of my continent was unsettled. More cities would have really helped with the production effort.
After settling Seoul on the southern tip of the north continent (hereafter referred to as Korea), I also captured a nice barb city right next to it, with fish, cow and rice. Renamed it Pyongyang. Peter had been in WHEOOHRN for a while - I assumed with Shaka, but a sword stack showed up on Pyongyang's doorstep, right around the time I was ready to start the espionage shenanigans. I had to gift that city to Korea. Since WK and Peter were WE's, they couldn't sign OB and Peter couldn't get around Korea to invade. I'm sure it would have taken him forever to build up a galley-based SOD anyway.
I got a mongrel GSpy from my Oracle city, and generated about 1500

myself by the time I started the colony cycle. The total went up to just under 6000

by the end. In total I generated 18 colonies.
Interesting bits about colonies:
- I could sign OB with probably about 40-50% of them, but I couldn't get the OB bonus. They always had 3

TR's with Korea.
- After generating the 10th colony, I broke the game and it started only generating Japan, alternating between Toku and random unrestricted leaders! This was nice, as it meant I couldn't get Maya late in the game.

Appropriately, Toku's 4th or 5th clone was still alive when the game ended.
- Each colony city gets 2 warriors. If they have somewhere to walk (i.e. if our borders are not completely enveloping the city), one warrior does tend to wander. I could avoid killing 2-3 warriors consistently in the first 10 colonies or so. Afterwards, they tended to stay in, as the cities were consistently in revolt after colony spawn. I was playing very fast and couldn't quite analyze why that is or how I could fix it.
- Colonies inherit the parent civ city culture and even motherland

! This one was a real nuisance.
-

generated against the parent civ on the same IBT that the colony forms does go to the clone, as well. The colony spawn is the last thing to happen, at the beginning of turn.
- I couldn't figure out any logic as to which city ends up being the colony capital. I know that Kaitzilla was trying to figure this out in the SG.
Game stats: 12 total cities (2 Korea, 4 colony-generating gifts, 2 Korean war success gifts, 4 permanently owned), 7 workers

84 spies, 28 chariots, 10 axes built, 136 warriors and 17 archers killed. 0 libraries, 4 courthouses. 24 out of 84 spies were still alive at the end.
I'll edit in other tidbits if remember them.
