Alrite so I've played quite far through today and yesterday, got liberalism and somehow circumnavigation (I just built on caravel to find cathy and hanni and ended up popping the event). I've got a pseudo GP farm going (Nottingham) and my future one Mecca. Captured the Buddhist and Hindu shrines and I'm building up an army for Mansa Musa.
Problems:
Cyrus is a monster and has vassalized Saladin who I could not kill off completely. Sal is culture cramping me and he needs to be delt with, however I'm not in any preparedness to take Cyrus.
I'm about to Make a civic change (mercantilism, free religion, free speech), maybe HR, but I"m not sure I want to take the two turn hit. I really need the switch however.
Save posted, comments are welcome.
You are making quite a lot of gold from foreign trade routes, it's likely that swapping to mercantilism will hurt you more than its worth.
Happiness is only a major issue in Damascus and Mecca, but the swap to Free Religion will cure this (Build a few missionaries to spread em around, you have accesss to at least 3 different missionaries), HR isn't necessary IMO. In Mecca's case just pump up the city's culture.
If you drop the Merc and HR changes a swap to FReligion and FSpeech will only take 1 turn. Be warned though a swap to Free Religion will seriously hurt your diplomacy
You have lots of gold in the bank, I would run at 100% defecit research to finish Printing Press and then go chemistry --> steel for cannons and grenadiers.
Build a few more Universities and get Oxford built in Hastings ASAP.
I'd workshop over just about all the grassland around Bahgdad and Nottingham's grassland farms to make it a super production city, although I don't know how good this will be as they don't get the +1
for caste system in Warlords.
Then smash Cyrus with cannons and grenades, your obsolete stuff in Medina can keep Saladin Busy while you kill his master.
I would avoid attacking Mansa till Cyrus is put in his place, you don't want Cyrus to vassalize anyonee else or give him an opportunity to backstab you when your off attacking Mansa.
