Open, Diplomatic
I still have a lot to learn about having the AI help me in research.
Our Technology
We hit the Industrial Age in 940AD getting Steam Power.
I waited to gift the scientific civs because I was planning on abusing my ROP with the ZuluAztec continent and didn't want anyone to know. Most didn't know Astronomy yet or were oceans away and needed Navigation.
I headed for Replaceable parts to help my railroading/Jungle clear efforts. Then I bounced back and forth between the top and bottom trees getting Corporation, Steel, and Scientific Method before being able to get Refining at 4 turn/tech rate. That resulted in all of the Industrial age techs being learned at 4turns/tech.
Iron Works
With steam power, the advisor tells me to build the Iron Works. OK! I forgot to look for Ironworks spots since I've only really built it twice. My investigation finds THREE candidates! The worst was on the island to the east of our start. (~70% corrupt) The other two choices were an R4 inner city outside of my new palace on the western jungle island that had become my new core and ... Pusan, my FP city built 1 tile SW of Persepolis. This is already my highest shield city so it's a no brainer. EDIT: At one point I was making 118spt with the factory/hoover dam. Not as impressive as Nata but then I didn't build any hospitals.
Last of the fighting
I used mostly MI and horses to wipe out the Zulu (honorably declaring from galleons at sea) and then the Aztecs (ROP Rape). I never saw the swarms of impi's that others mentioned in the last spoiler which was good because I didn't bring more than a couple pikemen. I think that the Zulu and Aztecs had stalemated and lost most of their units in an extended war. Chivalry wasn't available until the wars had started. Despite the lack of impi swarm, the little buggers still posed a challenge for my MI's. In two separate city seiges, I lost 2.5 MI to the top impi. Both times, the subsequent
archers scored a flawless victory. Guess I was using too much firepower.
The Aztecs built the Great Wall in their capitol, just as the Zulu were expiring. I used the ROP Rape to position my attack force next to the capitol and then declared. The four catapults I brought destroyed the palace! (and three other buildings.) I feared a game crash but when my troops took the city the capitol jumped and I think rebuilt the palace elsewere. No game crash. The Aztecs survived a few more turns as I moved my troops around to finish off the other cities.
The troops were repositioned to hit the Vikings from the two towns I had received in peace centuries earlier. The Vikings and English were honorably but quickly eliminated with knights and infantry, railing as I went. Many of the troops for this war were conscript infantry as I had very little military and the escort time from Zululand was taking too long.
AI Technology
The AI had researched Chivalry as their optional tech during my buildup for the Zulu war. I traded that to most to try to get them to research something else. Once the Aztecs were eliminated, I gifted the scientific civs to the Industrial Age and lucked out. Two go Nationalism and one got Medicine. I traded for both. I didn't expect to get any more techs from anyone so I just sold techs to Babylon and France for lux and gpt (not much).
I had learned Economics for Smith's, the AI learned Navigation but I got Magellan's anyway. Those were the only optional techs at the end of the game. No one even got Communism!
The finish
I realized a little late that I needed a TOE prebuild. As a consequence I wasted one turn researching Flight before I got it for free. TOE grabbed Flight and Radio and left me with 4 turns on Motorized transport. Pusan's palace prebuild was set to barely finish on the turn Motorized Transport was due just in case I got Fission for free. I double checked that I could slow it down by >4 turns if I didn't get Fission for free.
On the interturn, the science advisor asked me what to study next and Fission wasn't an option so I used the big picture to switch to the UN. The vote was held against France. I'd never traded contacts and nobody felt it important enough to sail over to visit Joan so when the vote was held they all said "Joan who?". Russia, Germany, Egypt and Babylon all vote for me, Joan for herself.
Diplomatic win in 1345AD.
(I think, the save is on my other computer.)
