Contender, going for Domination.
I feel that I played quite a good game this month, so I'll put up a more detailed spoiler then usual time. Don't know how it compares with the best games of the best players though since they don't post spoilers.
Hopefully it will be usefull to some people. I got a
domination victory in 1220AD using knights. Most of the time I was fighting only archers, propably the slow AI tech pace was a result of archipelago map. I expect my date to be beaten if somebody is brave enough to try a domination win with swords/cats/elephants because the AI were weaker then I expected. But we'll see.
The strategy.
Rolling several test maps had shown that it is unlikely that Astronomy is required to achieve domination. But the logistics is quite tricky on such maps, which may be a problem, especially on normal speed (I am more used to epic). So I decided that I would need somewhat more advanced units then axemen/horse archers to win, either macemen or knights supported by catapults.
The path to macemen/knights is not that long though, especially with some shortcuts provided by GPs. So the bottleneck will be food/hammers, not beakers. Because of that I decided
not to go for the CS-slingshot. It would require slowing down my expansion too much, ignoring essential techs and squeesing out every single beaker to get CoL early enough, and I did't want that. There is also another big disadvantage of CS-slingshot: learning CS unlocks the path to Paper, Eductaion and Printing Press, each of these techs having a higher priority for a GS. Not being able to take a shortcut to Astronomy offsets the research bonus of bureaucracy, so even if galeons are needed to win, not going for the slinshot is not a very bad thing.
I may still try to build the Oracle to take advantage of the industrious trait, but I will definitely not sacrifice growth in favour of research in the early game. The best tech to take for free in this case is definitely Metal Casting providing access to the Colossus wonder and cheap forges and shortening the path to knights. Cheap forges and cheap granaries together with the slavery bug are very powerfull. Other two wonders that are even more important then the Oracle are the Great Lighthouse and the Colossus. They will allow me to research Guilds at decent speed while still expanding rapidly and later in the game will help save me from an economic collapse. Another synergy with my overall strategy is that these 2 wonders both add great merchant points. So a city with only these two wonders and an engineer from a forge is guaranteed to generate either a GM or a GE. Either of these will shorten the path to Guilds by researching either Machinery (GE) or Guilds (GM) for free. Once I found marble I decided to also build the Great Library and National Epic to fully take advantage of the industrious trait and set up a nice GP farm. I decided to place Colossus and Lighthouse in one city to guarantee getting at least one GE or GM and all other wonders with National Epic in another city to maximise the GP points there. The other GPs may be used to research Astronomy faster (most of them should be scientists) or to start GAs.
Early expansion.
By expansion I mean not only settling, but increasing my total food/hammer output by any means, either by building or capturing new cities or by growing existing ones, improving land tiles, building granaries/forges, etc. To expand at the fastest possible pace I need to always invest resources into things that pay off the investment in the shortest amount of time. Usually building a settler to found a city near a bonus resource is better the growing to get a +1 food/hammer tile, about equal to growing to work a +2 tile and worse then growing to work a bonus tile. For Bismark building a granary and a forge is better then building a settler, etc. With military units it is a bit more tricky: 2 axemen won't get you anything, but a dozen axes is better then 5 settlers (and cost the same), so building units is better then expanding by normal means, but only once you are ready to produce them in relatively big numbers. In the early game I always tried to estimate the payback time for each choice and pick the best decision. Of course there were exceptions, for example you cannot delay building wonders too much even if it is good for the expansion since if you don't build them early you won't get them at all. Of course high-commerce tiles like the gold hill are worth being worked even if they slow down the expansion. The theory can also be applied to chopping. Without bonuses chopping provides 20 hammers, with math and a forge it will give 37 hammers. But hammers now are more important then hammers later due to exponential growth. It is quite difficult to estimate whether it is better to chop now or wait for math, whether it is good to build another worker exclusively for chopping, etc., so I made these decisions simply "by feel". The general idea though is that chopping is good when you are far from learning math and when you have just learnt math. But it is bad to chop shortly before learning math.
OK, now i'll tell the actual story.
I settled 1W of the start like most people did. The build sequence in the capital was worker, workboat, warrior, settler (capital was at size 4 as it started pumping out settlers working fish, pigs, gold and copper). Early research sequence was AH, Fishing, BW, Wheel, Agriculture, Pottery, Mysticism, Polytheism, Priesthood, Writing (order may be wrong). I did not beeline to Alphabet because I thought that the AI won't trade with me if they are isolated. I may have been wrong because when I did get Alphabet they did trade with me. If so this was propably a mistake that slowed me down a lot. I researched Polytheism and not Meditation because Polytheism unlocks Philosophy which would have made my backup plan of getting Astronomy with GSs useless. First city was founded near the cow to the SE, second near corn to the NE, third near corn and fish in the west. In 1600 I already had 4 cities and all the bonus tiles near them improved (except the fish in the west). Because of fast expansion and scouting (Berlin also pumped out a few warriors between settlers and grew to work more hills) I didn't have much problems with barbs. After settling these cities I built the Oracle in the capital. Marble was not yet connected because I wanted my second city with the cow in the first radius and on the coast. It was completed in 1480BC and I took MC. After that I invested into forges and granaries in my cities and later into axemen. My second city built Great Lighhouse (800BC) and Colossus (650BC). At this point I still didn't build lighhouses and didn't work ocean tiles and was mostly geared towards production. I wanted to conquer America ASAP since they were relatively close and had 3 gem mines, so I figured that their cities will boost my research rather then slowing it. The capital built a library though as soon as I got Writing and hired two scientists.
I attacked Washington in 550BC with about about a dozen axes and steamrolled him easily since he had nothing except archers.In 150BC he was down to one city at the northern tip of his island and I made peace with him to extort Calendar. During this time I also settled the rest of the starting island. After that I slowed expansion for a short while to get Guilds sooner. My old cities and the newly aqquired ones built lighhouses and grew in size to work the ocean tiles. I was researching at about 50%, but my GNP was by far the highest in the world, so as expected the conquest of America was great for my research. My research path after Writing was Math, Alphabet, Literature (to build Great Library), Monarchy, Feudalism, Guilds. Machinery was researched by the GE as planned. I traded for HBR, Construction, Currency and Calendar. In 350AD I discovered Guilds and switched off research forever. During that time I built boats for exploration and chariots for MP and upgrading later. I have explored most of the shorelines with my boats and circumnavigated the globe by 300AD. Great Library was built in Berlin in 75BC and NE shortly after that. Berlin became my main GP farm. By 400AD it generated a GP and a GS. Since it was already evident at that time that Astronomy is not needed for domination, I used them for a GA to mass produce knights and galeys. I also used my whole gpt to upgrade chariots. I planned to use next 3 GPs for a second GA, but when the third GP was born I was already about to win.
The main wars.
After that it was just a matter of transporting knights by galley chains and crushing AI civs one after the other, which proved to be rather tedious on this map. I didn't settle towns on empty islands untill late in the game because I could claim them quickly in the last 20 turns or so by mass producing settlers in home and in captured lands. In my game most of AI civs only had archers, so military expansion was definitely more efficent then peacefull settling, but I think that it is also true for better defended cities.
At first I expanded in the eastern direction, conquering Japan in 680AD and Persia in 840AD, later I opened a second front and attacked England and Spain simultaneously. Spain was destroyed in 1060AD, England was a bit tougher, they even had a few pikes, so they survived up to the end of the game. I also had a brief war with Russia, conquering a couple of poorly defended islands, but I made peace with them quickly and never attacked their mainland.
At 1000AD or so I started mass producing settlers to fill all the empty islands using galley chains to deliver them to even the most distant ones. I had a GA born in Berlin and planned to use him for a culture bomb in the last turns to claim some land in England without waiting for the resistance to end (or razing/replacing), but I messed up the english campaign. I didn't notice that the distance to their main island from the outlying islands is minimum 2 tiles and I couldn't reach it. I lost lots of time transporting a settler and waiting for the borders to expand to make a culture bridge for my boats. I also made peace instead of cease fire and lost a few more precious turns waiting untill I could cancel the deal. And by the time it was cancelled Victoria researched Feudalism which made it impossible to conquer her fast. Because of that I won by domination a turn before I could have used the culture bomb. In the end I had three unused GPs (the third one was born shortly before the victory) - very poor efficency
I stayed in slavery/HR/vassalge for most of the game, switching to caste system for the last few turns to expand borders of newly settled cities quickly. Before this game I prefered caste system rather then slavery, but the combination of cheap granaries, cheap forges and the slavery bug is just too powerfull. I have never used religious civics in this game and never even had a state religion. I decided that the lost turn is not worth the bonus.
In cities that I conquered early I built granaries, culture (obelisks and later theaters), forges, lighthouses and courts, so my economy was doing OK for the most part of the game. I built the FP in Osaka which was also a great boost, but I think I would have been better of building it in New York which was not that optimal, but could be built much sooner. After foundng lots of crappy towns in the end game my economy was ruined of course, but it didn't matter anymore. In the end I had about 1000 gold and -100 gpt.
