I wrote this about....15 days ago, so I'm just c/p it here right now so I'm first, then when I've got time, I'll correct anything that is wrong on here lol
When we left off, I had just taken a foothold on Hatty's island with my meager 4 unit army. Luckily she has little defenses and no walls. I use my galleys to move my axes across her island to Heliopolis, and while my newly created Swords and Cats are coming across the seas to help out, I take yet another city from Hatty when I take Heliopolis with a loss of a single axe(note, that's 3 cities with a total of 3 axes, 1 phalanx...I lost my first unit just now). Heliopolis is the holy city for Confuscianism, so now I've got 2 holy cities, with Memphis, the Jewish Holy city, close to my axes. Fortunately for me, Hatty doesn't realize the danger she's in, cause she's only seen my 3 axes...never seen my swords or cats, so she sails off to Arabia with 3 galleys full of troops, declares war on Saladin, and razes a city. She then kills one of my axes in Heliopolis with a cat, and to avoid losing the city, I sign a treaty with her.
Thus ends my first war with Hatty, 3 cities taken, 2 axes lost, 5 archers and 3 spears killed. Additionally, she gave me a mutual war bonus with Saladin, making him pleased with me as well. During the 10 turn peace treaty, I build up my army in Heliopolis to take Thebes upon the end of the treaty...she's one of my best buds again, but the cities I spent so much time taking are worthless unless I get rid of her culture. During this time, she founds Byblos on the Hourglass island north of Corinth, pretty much where I had planned on putting another city.
Unfortunately, at turn 9, Hatty adopts Vassalage...means she now has longbows, which means I've got no chance of beating her with axes and swords...I need Maces. I've already got Machinery, so I need CS still. Everyone has it, but no one will trade it to me, until Izzy decides I'm more of a friend than an adversary and is willing to trade it to me for Paper and Divine Right. A steep price, but its worth it because I need to take out Egypt soon.
I've been running a huge deficit(-40gpt) pretty much ever since 1AD, funded by war spoils, unbuilt wonders, and selling my world map to anyone with cash. I discovered during SGOTM3 that while a WM is helpful for us, the AI doesn't get much benefit from it, yet is willing to pay good money for it, quite often too.
I use my gold surplus to upgrade 4 troops in Heliopolis to Maces, and declare war on Egypt again around 1100AD. At this point, I bombard Thebes to 0 defense, then the next turn suicide 4 cats and take Thebes at the cost of 4 cats and a Mace. I move my troops toward Memphis, and take a detour to raze Pi-Ramesses, then another city that Hatty sent 2 longbows to found lol. I move in on Memphis, bombard it down, then suicide everything I have on it to take it, giving me 3 holy cities...unfortunately, I find that Hatty never built a single Shrine! I make peace with Hatty, who has just converted to Islam, which she also founded. At that point I realize the stupidity of being Jewish still and convert to no religion, immediately bringing Saladin and Izzy both up to Pleased with me. I then concentrate on catching up to Cyrus and Caesar in tech, and building up my infrastructure, cities, and getting rid of my deficit. Cyrus hits Liberalism while I'm ending my war with hatty, while I'm still researching Printing Press(not required for it, I know, but I had a GS lightbulb it, and wanted to finish it first, since I had so many towns and villages).
I made a few stupid civics changes, such as changing from Slavery to Caste System on accident, forgetting to change to Bureaucracy or Hereditary Rule, adopting Mercantilism, which didn't really help me because I couldn't use Representation yet. But I began to catch up to Cyrus and Caesar slowly...founded 2 more cities on the gems/gold island SW of our starting position, founded 1 more on the island SE of our starting one, founded a city to the NW of our starting positino to grab the horses. I captured 2 large barb cities up to the far north....this ended my expansions.
Techwise, the most important lategame techs for me were Liberalism, Astro, Electricity, Radio, and Economics. Caesar had converted to Islam, and 2 turns before I researched Liberalism, he asked me to convert. To make him happy, I agreed, knowing I'd switch to Free Religion immediately upon discovering Liberalism. That cost me a turn, but gave me a bonus with him. I was able to trade Astro for all the mid-late game techs I hadn't bothered with, Nationalism, Banking, a couple others, and a ton of cash. Liberalism I traded around for cash, Electricity I traded for 2 techs from Cyrus, 2 from Caesar, and 1 from Saladin...along with cash. Radio I traded for 2 techs each from Caesar and Cyrus, finally catching up with them, while Economics gave me Free market and allowed me to finally have a larger GNP than anyone else. I got a GE luckily from Thebes in the mid 1700s, and a Merchant from Athens at 1800AD. I sent him trading to Rome, netting me 2600 gold. I then went to 90% research for the rest of the game. Mass Media researched in 1814AD, GE used on the UN in Elephantine, and manually built the last 17 turns of it because I didn't think and switch to Univ. Suff. once I had access. Switched to Emancipation in the 1820s, didn't switch to US because I didn't want to lose the bonus I had with Cyrus for Representation.
I was feeling worried about my military, because I didn't really have much of one after taking down Egypt, so when it was available, I got defensive pacts with Cyrus and Saladin...I had hoped Izzy would sign one with me too, but she didn't like me enough. This made me less worried about my military, but more worried about the vote...Izzy was +7 with the two defensive pacts, but +9 without them. Luckily, Saladin declared war on Hatty, ending one of them in the 1820s, and once I built the UN, I ended the defensive pact with Cyrus, bringing Izzy back up to +9. I had Saladin and Cyrus both Friendly with me and +13/+14, so I was guaranteed their votes(Caesar had been #1 in pop the entire game, although he was friendly +11 with me as well)
UN built in Elephantine in 1832(immediate vote, I win Sec Gen), and in 1836, I discover that I have Cyrus and Saladin's vote, but not Izzy's for Diplo Victory...I'm 40 votes short and she has 96 votes...she's also at +9 with me, but I can't seem to get her happier with civics(doesn't want my civics and can't access her fav civic), mutual war(doesn't want to declare war on Hatty, even though Saladin and I are already at war with her)...the only way to make her happier with me is to adopt her religion, Hinduism....unfortunately, I have every single religion present in my civilization EXCEPT Hinduism. Thus, I do the only thing I can think of...search my map for an Egyptian city that has Hinduism in it...I find one, send over a Galleon full of Maces and a cat. Luckily, Saladin has been bombing it with a frigate, so its defenses are gone. I conquer it, immediately switch to Hinduism(a calculated risk...no one else is Hindu so I risk alienating Saladin if he cares more about religion than I thought he did, and I risk Caesar deciding to declare war on me(he is +13 friendly with me before I switch, and luckily, +10 friendly with me after). Once i take the city, I play it safe(or risky again) and get a cease fire with Hatty...I don't want a 10 turn peace treaty in case I lose Saladin's vote, but I don't want to lose the Egyptian city immediately and lose the ability to have Hinduism as my state religion. I get lucky and the vote is the very next turn...I submit it and win a diplo victory, 1844. Score of 18k
It wasn't an early victory...but I'm happy with it since it was a true diplo, everyone was friendly with me except Hatty at the end, even Caesar, my rival, and because I played on Challenger, on a difficulty level I couldn't have beaten just a few months ago! Additionally, I didn't catch up to Caesar and Cyrus in tech until I researched Radio and traded it to both of them for 2 techs each...they were both resaerch powerhouses, and if I'd played my opening game better(expanded faster, not spent as much time and focus as I did on my Egyptian war, then I could've finished much earlier, I think)
Summary: I made many civics mistakes, but I played the diplo part very well. It was a great decision to leave Hatty alive as it didn't tie me up any more, and it gave everyone a civ to hate on unilaterally...thus allowing me to keep civs like Saladin and Izzy friendly with each other despite being opposing religions.
I gave in to every demand made of me by my friends, including civics changes(I ended the game with Theocracy rather than Free Religion because Saladin demanded I use his favorite civic, it kicked me back into Islam, but I switched to no religion ASAP), adopting religions(Judaism for Egypt, Islam for Caesar, and voluntarily adopting Hinduism for Izzy at the end), gifting techs(I gifted 7 or 8 techs to Izzy attempting to gain the 'shared technology with us' +), and I even used the fact that if you are pleased or higher with a civ, they don't get mad if you ask for something...such as cash or gpt. I did both, getting 11 gpt from Saladin, Caesar, and Cyrus at one point when running a big deficit, and getting 400 gold from them later on when I needed it to fund my war with Hatty.
I never led the game in score, and had a very mediocre score of 2500 at the end, but if for some reason Diplo had failed because Izzy wouldn't cooperate, I had an easy run at a mid-late 1900s Spaceship thanks to my huge economy, but low production base by the end.
