Decided to start with Gilgamesh (620 AD), since it should be a breeze and it times nicely with getting rifling, so I can go cavalry on Genghis. Was super easy, took 4 closest cities in 4T and capped 700AD. Whipped HE in capital, it's the best spot and

is a problem for my empire AND

is rather useless very soon. Can't think of a tech I need after rifling really.

-generation in York was kind of a fail, should have just starved during GA, now I need to whip a market to get the last

out and I think only a GM is worth something. Can bulb chemistry with a GS, but meh, I don't think I do much with steel even.
Declare on Genghis 5T later (800AD), just had to spend some time moving troops and upgraded almost all of my army to cavalry, since I had the money and the plan is to shut down research entirely. 5T later from that (900AD) I had captured 9 cities pretty easily, as there is just not much even an unit spammer deity AI can do to 30 cavalry if he doesn't even have gunpowder. I'm sure he had a stack somewhere fighting Hammurabi, but it's a long trip for him. I chose to cease fire now, as "Stop fighting amongst our faith" would be a disaster since it forces 10T peace. It's annoying to lose all war success, but also Wang should break free and things will be easier.
Wang broke free as expected and I re-declared on Genghis 940AD. Ignored New Sarai as it's slow to reach and just pushed towards NE. No sign of anything that stops me yet. Karakorum had Mids, so I wanted to test rush-buying and switched into US.
@krikav I don't think it works as you think it does? Any

multiplier buildings have no effect on the cost. Once you have

invested, the cost to finish the build is 3*

, same with or without a forge. I don't have many forges, but I chose to not rush-buy in them and spent my money on ~3 cavalries per turn mostly in cities that have barracks. I didn't bother building them in captured cities really, just better to get units as most are mopping up weakened enemies anyway.
3T later finally see his stack and it could inflict some damage to me. It's important to get it into open field and be the aggressor (cavalries have 30% retreat, no defence bonuses). Him putting that stack to Shushan is an issue, so I had to come up with a trick.
Bribed Hammurabi to make peace with GK for paper, then gift Shushan to Hammurabi. Sacrificed workers (no use for them anyway), which was a bit unnecessary though. Anyway, his main stack moved to the forest so I gained a full turn of healing and moving more troops to Samarqand. Next turn he moves 1W and I wipe most of his stack out with barely any losses and he's willing to capitulate (1020AD). Declare on Hammurabi immediately and next turn I can move into position to attack.
Mainly HAs, some bowmen and a single longbow. Ok buddy, you've been having a hard time this game I guess.

I didn't even need to take the city, just win some battles and capitulate when he is willing to talk (1050AD). Declare on Wang immediately, take one city and he is done next turn (1060AD). I didn't really need to stop to heal a lot in this game, though I had a super-healer chariot. My best cavalries were also reaching march, which makes things a bit easier. Declare on Joao 1080AD.
These were the typical odds in every war, first attacker roughly 80% (to survive) so with this amount of units poor AIs have no chance. Also note I did really kill of the research and used all money to buy more cavs. More power, more attackers, everything is easier.
After Lisbon Joao was done (1110 AD).
Immediately declare on Washington with a stack I had prepared in the core area. Captured cities are building wealth.
Took Bantu, killed some stray units and he was done (1130AD).
So 1140AD victory it is, both conquest and domination reached on the same turn.
So the war phase in total lasted 620AD-1130AD, that's 32 turns to capitulate 6 AI. I always try to preach for swift, efficient wars and I think I managed to do exactly that.
Thanks for the game, AcaMetis, had a blast!
