It's hard to give too much advice on your game without seeing a save. But, some additional advice to add to my last post.
- I chose AI's that were not financial (to minimize their teching) and not protective (so they would be easier to conquer). While I hadn't thought of it, in retrospect, I agree with Padraig's observation that creative should also be avoided (I had one creative AI, but she ended up on the other continent). Next time, I'll avoid those as well.
- I wish I had thought to turn off vassals. In my 1770 win, I had problems with AI's vassalizing. This was not an issue in the 1340 win.
- I really focused on producing units. I built very few buildings besides barracks and courthouses in most cities. Other than that, two early monuments in captured cities that needed to expand to grab a resource, 1 granary and 1 forge (in my capital), heroic epic in capital, and forbidden palace somewhere. Absolutely nothing else, zero libraries, no other granaries, etc. I did minimal whipping, so I didn't waste the time on granaries. A few extra early axemen are more important to get a quick jump. Besides, with the constant war weariness and whining to rejoin homelands, I didn't want big populations in my cities.
- Speaking of concentrating on early axes, I built 1 worker and 0 settlers. Ended up capturing a couple of dozen workers though.
- No GP farms... every city was a Hwacha farm! I build 179 Hwacha's.
One of my captured cities did pop a Great Artist (from a captured wonder), I had zero other GPs.
- I teched as I suggested in my previous post. Find copper, beeline to construction, head for CoL and CS. Picked up music to build culture (no early religions on my continent), then drama for culture slider at the end. I guess I did get paper thinking I might need to tech to cavs. This was a waste, Hwachas took me to the end. A stack of 30 Hwachas will have no problem with a city defended by longbows, macemen, and oliphants. Their collateral damage really is devastating versus defender stacks. I traded paper for machinery and build a couple dozen maces at the end just to travel with my Hwacha hordes.
- However, having said all that, teching was really secondary after construction. Cities focused on building Hwacha's, not on becoming learned. Think barbarian, not academia.
- Honestly, I paid little attention to diplomacy. I managed relationships with a big stick.
- Taoism eventually was discovered on my continent and spread to me. I really wasn't paying attention, should have switched to it right away for Theocracy. I did eventually.
Good luck, I hope this helps... Personally, I would like to see more open sharing of strategies and tactics during gauntlets so that we all move the state of the art forward. I'd love to see you learn from my experience and knock me into third place.
