I have a great sense of satisfaction and achievement with this victory. I have spent the last 2 1/2 months getting my butt kicked on this game. This is by far the toughest victory that I have accomplished in Civ IV.
I played fractal, low seas, Agg AI, No Random events. I added Qin Shi Huang and Huayna Capac with the required four. This was the key to my game. I played about 70 different games for this one. Most were abandoned quite early. I played about 20 games out to post liberalism teching. I really only had one game where I was close to victory. In that game my spaceship launched about 5 turns too late.
Per STW's recommendations, I had been trying to play Big and Small for Sushi leveraging. There are two main problems with this:
1. There is too much love between the required civs. The four required civs usually don't like Willem early on, but they usually get along quite well by mid game. Bribing wars helps with this, but then you often get caught in the diplo triangle. Bribing peace is essential to prevent anyone from getting too strong and running away with the game. I had to give up a lot of techs with bribing. There is not enough room on Big and Small to add low peaceweight civs.
2. Buying sushi resources gets really expensive. Peaceful expansion doesn't give much land. Most cities have quite a bit of overlap. Therefore, you have less land to secure resources for trading for happiness and sushi resources. Most Sushi resources can be initially bought for 5 gpt initially. This quickly escalates to 12-15 gpt. Not only does this become expensive, it really helps the AI.
A third and lesser problem is the early culture push from neighbors. Liz, Mansa, and Willem push culture the hardest, but Wang Kon will push too. Sushi helps tremendously with the culture push.
I suspect a tropical forest map works well with state property. I hate the jungle sprawl, so I avoided this map. I chose fractal for the choke points. Most AI are within reach early on for trading. I added Qin Shi Huang since almost everyone would hate him and he would like me since I ran bureaucracy. Similarly, I added Huayna Capac since I would run HR for quite a while.
I started with a two corn (one irrigated), two riverside hill gems, a riverside gold, five forests and 8 river tiles. Unfortunately I had to settle on a non-riverside tile to get all the goods. I teched Agr>BW>Hunting>Wheel>Pottery>Writing>Alph>Aesth then traded. Qin Shi was surprisingly the early and mid-game tech leader. I eventually ran hinduism, as that was the safest religion. I didn't get a strong GP farm going, but I still teched well and bulbed (my only tech bulb) most of liberalism and eventually astronomy at 370 AD from liberalism. I think the Agg AI setting slowed AI teching enough to allow me to be the tech leader at this point. Qin Shi was the first to discover Medicine, about three turns ahead of me. I did actually found Sid Sushi once I got Medicine. I then pushed to Superconductors for laboratories. I beat everyone to plastics, and computers to get the internet. After computers, I had a quirky tech path. I went genetics> superconductors> fission> fusion> ecology> satellites> composites. I was hoping to pick up satellites and composites from the internet, but got no such luck.
I could not have been more fortunate with wars in this game. I was never declared upon. I joined two wars at Qin Shi's request against Mansa Musa and never had any battles. I was able to meddle enough with bribing war, bribing civ changes and bribing religion changes to cause enough discourse to keep everyone off my back.
It turned out that Sid Sushi helped, but not as much as I liked. I had a few sushi resources and traded for several. Wars led to resource pillaging that limited seafood availability. My big and small games taught me that more sushi resources are not necessarily better when you are trading for them. My fractal map had a large shoreline that provided quite a few seafood resources.
I couldn't pop a great engineer, and Liz founded Mining Inc. and Creative Constructions within three turns of each other, and somewhat early by AI standards. She spread Creat Const. to me. I spread it to a few cities. Prior to this I was considering state property for my final push. Eventually, Liz killed off one of my neighbors Wang Kon. For the first time in all of my civving, Liz gifted me Pyongyang. She had spread Mining Inc. there before she had captured it. This allowed me to spread Mining Inc. throughout my empire, and giving much needed add'l hammers.
My expansion went very well. I had two choke points and a good chunk of land, some of which was tundra. I didn't have a lot of fresh water, although I was able to spread farms via a long irrigation chain. Early on, Wang Kon put one city right in my face in a prime location. He lost it in a war and eventually it flipped to me. I took one barb city, and settled the rest. I eventually had 14 cities. I had enough land to get two iron, one copper, one coal, three uranium, two aluminum, two oil, and marble. I got stone too late to be of any value.
Near the end of the game, I had a strong tech lead. Actually everyone built their Apollo Programs well before me. I built all the parts in quite a hurry. I was able to trade uranium and aluminum safely to get several happiness and corp resources. Willem overtook Liz in the culture race. Willem was about eight turns closer to victory than me at about 36 turns out. I ran bureaucracy all game and was able to bribe Willem out of free speech for the rest of the game. I also bribed him to representation at another point that gave him 4 turns of anarchy. I beat him by about six turns.
My 14 cities were two, heavily cottaged cities, one GP farm that was a late convert to a production city, two strong production cities, two hybrid cities, and seven weak production cities.
This is the most effort I have put forth for any game. I am thrilled to be able to move on!
