This is how I settled.
Angor Thom and Angor Wat I settled aproximatly the same time, one settler from each city. Wat to block of the AIs and gain a good foothold up there, Thom to share the wheat and to claim the horses.
After that it was Nagara down south, mostly to offload the capital from the corn but also to aquire two more happines resources quickly. (Ivory, gold, fur and silver early on, this was really nice! )
Rajavihara was an awesome spot to spam cottages, something that was really needed.
Techpath up to this point was myst (from hut), AH->BW->Agri->TW->Pottery->HBR->Archery->Writing->Math, and now I'm teching toward alfa.
I have a settler standing at the copper, because I got some quest that required me to build 7 stables. I did so and got 7 horsearchers (all with 0 XP).
I declared this turn, I was probably abit too careful and could probably have gone for it earlier. Had 22 HAs at this turn, but some where still in my cities or on their way west.
Had some HAs on his other side too, to quickly take a few cities, and steal his workers.
He had built the oracles, which was really nice!
When he just had one small pop1 city, he was quite generous.
ALL my cities had to work whatever commerce they had, and every city had to build research to reach currency in time before I got into strike. I didn't plan for that, and I guess Tokus westernmost city was a mistake to not raze.
It was quite a pain to have 4+ cities working unimproved riverside plains, and unimproved coast, instead of pigs and corn.
This is the situation when I got into currency.
I did not continue toward CoL, but instead started to snail my way toward Feudalism to enable vassals and to get toward Knights.
Here at T84 I was ready to attack Wang, but when I inspected his cities he had a massive build in Seoul, and he would not trade me Sailing, so he was on his way to complete the great lighthouse.
I consulted Kaitzillas excellent guide, and calcultaed that it was just a few turns away, so I stalled my initial attack.
I then go around and make a few arrogant demands (which they oblige to) i demand Sailing from Genghis, and Polytheism form Kublai.
I also trade my meditation for Qins preisthood.
T85 I trade currency and metalcasting for monarchy+monotheism with Wang. He won't be around long to trade away those techs.
Only now I declare on Wang.
SH and even faster expanding borders doesn't hurt, and GLH will be a life saver economically.
T90 Mao finishes ToAR, which I had chopped 3 forests into.
250 failgold sees me to feudalism.
The 7 unupgraded horsearchers I got from the quest, plus some more that had been built, is now moving toward Qin, and I declare on him T91.
I still have no clue where Genghis is, but it's pouring down missionaries from this jungle, so I move up.
