I took a look at the save you posted. I noticed some things with your game.
1) You went for Polytheism as your first tech to found a religion. This is a big no-no on higher difficulties. The most important thing is improving your food resources early on in your case the Corn. To make matters worse, the religion did absolutely nothing for you here and you adopted another religion which spread more widely. Don't found an early religion.
2) Researching the Wheel before Bronze Working was another big mistake. BW enables Slavery for whips and chops both of which are extremely strong.
3) You settled your second city super late on turn 47 (2160 BC) and very far from your capital. You settled your fourth city really really far probably with the idea of getting Horses. Settle your first few cities closer to your capital to reduce maintenance costs and enable you to connect the cities for trade routes. I would have probably settled the second city 1 W of the Copper around turn 35. Generally when you have cities around you within 5-6 tiles from your capital that have food, found them ASAP. People often have 5-6 cities by 1000 BC and a very compact and connected empire. The way you settled you may have claimed more land (debatable) but you killed your civ early with higher maintenance and didn't profit from your powerhouse cities early.
4) You are building way too many buildings! I'm looking at your capital that has like 20 buildings. I would have built the Granary, Library, and Forge. That's about it. You aren't going the military route here and thus don't need Barracks, Stable, Dun etc. and a lot of other buildings especially like Markets, Grocers and religious buildings just aren't worth it.
5) You've got a ton of obsolete units costing you gold in maintenance. 1 Gallic, 7 Axes, 4 Archers, 3 Spears, 1 Chariot... These units aren't going to do squat against any army that attacks. Disband them and you save 16 gold per turn. You'd be several turns ahead in research by just doing this many turns ago. Units are generally too expensive to upgrade.
6) You focused a lot of your research on the bottom of the tech tree. If you made a focused Liberalism --> Military Tradition beeline you'd be a lot better off. You're behind pace technologically for 1300 AD because of this. Not tech trading does slow things down a bit though.
I don't remember the game exactly, but here are my explanations/justifications:
1) Yeah, considering I was playing against 5(?) AI's, I reckoned that I only got one chance to found a religion, so I went for it straight away. I later ended up converting to Judaism because literally every civ had it, so I made some missionaries and switched (spiritual, so no anarchy).
2) I think the reason I got roads before BW is because I had marble in my capital, and wanted to go for an early oracle.
3) I settled late because I wanted to grow my capital first. I just had some really good tiles there, and I figured: if 1 extra tile gets me, say 3 extra food+production, then assuming a settler takes 100 food+production, it shortens the amount of time needed to get the settler out (so tile "growth-->settler" might be faster than just "settler"), however, the larger your city, the less this applies. What I did was basically: develop capital--> pump out some 4 settler one after the other.
4) Yeah, I probably go for too many buildings. Keep in mind that my beaker/gold was about 70/30, and even less earlier on. Markets give as much (+25%) as libraries (though they cost about double), so, particularly in your capital they seem like no-brainers to me. The Dun was useful because of the promotions, barracks definitely paid off as well. Monasteries give +10% research, so again they seem like a good investment for the capital to me. Temples basically give the repression +1
without having to put a unit (costing upkeep) in there.
5) Yeah, this is a difficult one. The thing is, If I got rid of them, I'd be even more vulnerable. Ideally I'd want to replace them with better units, but until that time, I keep them, because that 5 damage +50% against melee is still significant. Nevertheless, archers are really pushing it by that time haha. Probably not worth the upkeep.
6) Liberalism isn't all that good imo. Keep in mind that it costs 1400 beakers, which is a lot. It's only justified to get it if you can immediately research something like astronomy, chemistry, nationalism, printing press, because liberalism itself is near worthless that early on (US and free speech don't become useful until late industrial). those expensive techs that I just named aren't all that useful either. I'd much rather have banking or engineering.
You definitely make good points though, and I was probably too focused on getting early religions/wonders/territory. Thanks for the analysis!
