I had some computer problems and other stuff going on that made me play this over a drawn out period and not keep very good notes. But here goes…
My hope for this game was to score an early Diplomatic win by using the Apostolic Palace. To do this, I figured that I should, in order:
1. Establish a sound economy, production capacity, and military
2. Start building the Oracle
3. Explore the world
4. Research the prerequisites for Theology
5. Use the Oracle to get Theology for free
6. Spread Christianity to at least one city in every civ
7. Generate a Great Engineer and use him to build the Apostolic Palace
8. Win
I settled in place, built a worker, and researched some basic economic and military techs while producing a couple of workers, settlers, and some defensive units.
By around 1850BC I had 3 cities, the capital; Gondar sited to get marble, ivory, and food; and Lalibela over by the flood plains, seafood, and copper. Around this point I began work in earnest on the slingshot part of the plan, researching Masonry, Polytheism, Priesthood, and Writing. I started work on the Oracle in 1100 BC and completed it in 825 BC, the turn after I researched Monotheism and founded Judaism in Gondar. Per plan I took Theology for the free tech and established Christianity in Lalibela.
While all of this was going on, I built some Work Boats, and later Galleys, and sent them out exploring. So I had a pretty good idea who was where, although it took me a little while to find Darius and Suv and until then there was a possibility I’d need Optics to reach everyone. I founded the last of my really important cities around the same time Christianity was established, Addis Ababa was a production center near all that Ivory and forest.
Everything up to this point had gone really well… but from here on out lapses in judgment and the difficulty of managing relations with all the AIs made things a lot tougher. I was fortunate that only two civs had any religion whatsoever: the Byzantines and the Celts had each established one. I made it a priority to spread Christianity to exactly one city in each of those empires ASAP. I needed them to have some Christianity or a diplo vote wouldn’t be possible, but not very much since they would surely never like me much.
After that I tried to spread Christianity to everyone else as fast as I could. It spread to Russia and England on its own, but I had to send missionaries a long way by boat to get to Persia and Khmer. Very unfortunately for me, before I could get both of those two converted to Christianity, a war broke out between them. I could have joined one side against the other and tried to keep my new enemy’s Christian population small. But they were both so far away that I didn’t think I’d really be able to influence things much. I decided to refuse both of their requests for aid, harming relations with people whose votes I wanted.
What may have been a mistake was that I continued to spread Christianity among these four civs beyond the 1 city per empire that was an absolute necessity. I wanted to be sure they would all convert to, and stick with, Christianity, so that they would all get religious bonuses with me, and with each other as well (hopefully preventing more wars). Which pretty much worked. But some of the civs actively spread the religion within themselves as well, and the end result was that there was a very large Christian population out there before I’d even started on the Apostolic Palace. I’d need to get a lot of votes from other civs to win, not just one other civ on my side.
Speaking of the Apostolic Palace, I followed through with generating an GE to build that, and completed it in 475 AD. I certainly could have finished it earlier if I’d wanted to, but there wasn’t much point in starting it until I’d spread religions around a fair bit. And by then the GE wasn’t too far away.
Churchill was my opponent in the initial vote for resident, which I won easily, but Russia became #2 in Christian population after that. I prepared for vote #2 by giving bribes to England, Persia, and Khmer and proposed a Diplomatic victory, which failed. England was with me but Persia and Khmer were for Stalin. Disappointing but not too surprising given that my relations with Persia and Khmer were good but not great. I kept at it, and in the next vote Persia was for me as well, but even though Khmer was something like +12 for me and +10 for Stalin, he still voted for Russia. Apparently he still held a grudge about my refusing to help him in wartime. And without him I was something like 40-50 votes shy of victory.
For too long after this second vote, my play was kind of aimless. I kept working on boosting relations with Khmer via gifts, and also spreading Christianity to more English and Persian cities. Which was good as far as it went. But what I really needed to do in addition to this was concentrate on building more cities and growing my existing ones as fast as possible, and for too long I neglected this in favor of nice but unessential infrastructure. This wasn’t well and truly driven home until 2 or 3 votes later, when Khmer finally did come round to my side, but I still failed (by 3 votes) to get the necessary supermajority.
By now it was something like 850 AD. I finally committed myself to a population-first strategy by, for instance, not whipping things to completion anymore. I also built a bunch more cities on the outlying islands and wherever there was enough space left on the main continent to be worthwhile. Unfortunately for me the Khmer and Persians fought another war. One which I quickly voted out of existence—but not fast enough to prevent them from asking me for assistance. Which I once again refused, and which once again meant they wouldn’t vote for me.
By the 1100s I’d concluded I would have to fight a war with either Justinian or Boudica to get more land and population. So I started building my military up as best I could while still focusing on growth and growth-related techs. Boudica declared war on Churchill in 1290 AD and I joined soon thereafter at his request. I did OK to start with, capturing a city, but my reinforcements only trickled in and it turned into a long stalemate. But after awhile I hit upon something I should have thought of earlier, which was bribing Khmer to join me in the war.
With the mutual struggle bonus pushing our relations up to about +16 (compared to +12 for Stalin) the Khmer started voting for me again. And in 1495 AD this was finally enough to get me a Diplomatic Victory. This happened to be the same turn I researched Liberalism—which I’d put off for awhile—and took Physics as my free tech.
So my strategy worked! But it would have been a lot more impressive if I'd pulled it off shortly after completeing the AP, in say 600 AD. Oh well.
