Ok. The plan:
1. Egypt needs to die. Curraisers/Cavalry was one choice. I chose Rifles because:
a. Rifles don't die against medieval units.
b. I will need the Rifles that killed Egypt for Darius.
2. Darius needs to die. This was going to be tougher because Darius WILL have Rifles by the time I'm ready to attack. BUT most of his cities are coastal. If I can launch a massive amphib assault of death, with suicide cannons and rifles, I can pretty much take him out in one turn.
3. Hammurabi needs to die. This should be easier. Once Darius dies, Hammurabi is next.
Hence, the tactics:
1. Screw Education. My people don't need to be educated. They're stupid anyways. They shouldn't go to Universities. Instead, they should learn how to pick up a gun and shoot people. Hence, gunpowder first, followed by beeline to Rifles.
2. My people don't deserve Caste System. They're better off and HAPPIER as slaves. So I switched to slavery and immediately whipped up some infrastructure.
3. I need Banking. And Nationalism. Do I tech them myself? NOOOOOOO! Tech trades for them. Along with Guilds, Compass, etc.. Granted, this speeds up Darius's tech, but I need these techs.
4. Prior to getting Rifling, I build muskets and trebs. I also build lots of banks and grocers. Why? The moment I get Rifling, I will upgrade all of my muskets to rifles, AND THAT WILL TAKE MONEY. Once Rifling went online, I immediately turned tech to 0%, and money to 100%, utilizing the banks, and grocers I built.
5. Once I had enough, I had three groups: Army Group North, Army Group Central, and Army Group South. The first targets are obvious.
6. The war started in 1475 AD. It ended in 1550 AD. I lost maybe eight trebs due to suicides, and 6-8 rifles, total.
7. Next step: Get Assembly Line (infantry!), Astronomy, and Galleons/Galleys. I'm behind in tech, but with beelining I can probably catch Darius in time. Otherwise, I will have to wait for tanks, marines and fighters. Either way, Darius is going to go down long before the space race.
8. Once I have overwhelming force, I destroy Darius.
9. P.S. Eventually I do get Education. But that was during the war on Egypt.
10. P.S.S. Egypt had the Pyramids? OMG. I guess looking at it from a historical perspective, this shouldn't surprise me. Police State and Representation, HERE I COME!!!!
11. Now that you have the Mausallos, and a GP, and A LOT MORE LAND, I'm going to GA CONSTANTLY after the newly conquered lands recover.
12. Slavery is very good for newly conquered territories. Whip, whip, whip to rebuild infrastructure. Your cities will starve anyways, so use them by whipping them first.
How I could have done better:
It was sloppy. I'm not particularly good at using Spiritual. Eventually I just decided on Slavery/Theocracy/Bueracracy- with occasional switches to Nationalism for draft.
I need to remember that under Hereditary Rule, it's a good idea to keep units in cities, instead of moving them out PRIOR to the assault.
I probably should have gotten Education and Universities first. Eh well. Rifling took a while to research.
EDIT: Played up to 1804 AD. The invasion is underway.
Universal Suffrage + Lots of Towns + Lots of Cities+ Free Speech = Good.
Should have gotten more destroyers for bombard, and also too much infantry (lacked combustion for a long time), but oh well.
Persia is very, very dead.
