Sadly i forgot to save my game the first turn and the autosave got overwritten, so this game cant be accepted i guess.
I still want to post my result for those interrested.(Its rather long, so be warned

)
Basically i won at
turn 240 - 1650AD but with abit of luck(only 2 cultured city states

) and better use of great scientists it should be possible to shave 10 or so turns of that(maybe more)
I will do some changes in my next game that will hopefully improve the date.
Before i started i had the following plan:
- Make sure to have marble, one other luxury and a long river at your starting position, aswell as a good amount of hills(didnt care much about forrests. I only find them really usefull late in the game with my approach) Btw i had no wheat so that would be nice to have next game.
- Go with one city only and a bunch of puppet cities.
- Get allied with maritime city states first. The food bonus alone for your capital + puppet cities are just better than the extra culture you get from cultured city states. Big puppet cities means more research, more gold and from what i can see also more culture over time from the improvements they make... so id say ally with maritime states first
- For research i wanted to beeline to renaissance for the the full food bonus from maritime states, and unlocking the freedom tree. That would help my capitol grow big to complete wonders faster, get a nice culture bonus from constitution, and to let my puppet cities grow faster.
Now i had different stages i went through:
First was to get to patronage asap by completing great library and philosophy at the same turn(in the meantime make Stonehenge ofc) I got mining from a hub so i went to get masonry first to sell marble early.
Instead of going for civil service i went for theology. There is alot of reasons why i find that more efficient.
First of all you will be able to unlock the freedom tree and get the max food bonus from maritime cities faster, by going Theology -> Education -> Acoustics.
That is absolutely key as you want your capitol to grow big very fast very early.
Second of all: It will let you get to Archaeology faster also.(and astronomy to explore and meet the remaining AIs and city states)
Third of all you wont be able to really use civil service in the beginning anyway, as you want to focus on hammers, to complete library, oracle, national college.
I managed to get to patronage in 57 turns. And chose the city state bonuses. At this point i had saved up 1000 gold to ally with two maritime city states.
Also i tried to push my first golden age as late as possible by selling my luxuries.
At turn 84 i used a great scientist to invent acoustics the same turn i invented education.
At this point i went for
consitution for the culture bonus.
I also picked
Scolaticism as i would try to ally as many city states as possible, and that research bonus from them is just sweet.(accounted for ~40% of my research at turn 84 xD (with 4 allied city states)
Lastly i also picked
Cultural diplomacy. The reason was that i needed that happiness to reach my 1000/1000 second golden age faster(just after chichen itza is completed). On top of that the extra happy faces would also help me puppet more cities. Its a good combo to have with my focus on allying maritime city states before cultured ones, bacause my empire will pump out more science, gold and imo culture also(your puppet cities seem to focus on making a few culture buildings like monument, garden, monasery, and putting specialists in them.)
After acoustics i got civil service. At that point you have the citizens to spare for food tiles, after you have made important buildings like library, oracle, national college and maybe temple(i didnt make it)
Also your capitol at this point is big enough to really earn a healthy food bonus from the river tiles(get your capitol to size ~10-12)
Finally after almost 100 turns i went to war. Made 4 horsemen and got one from a city state which was plenty to conquer 2 AIs. At this point i didnt want more than ~5-6 puppet cities with some different luxuries. More and i wouldnt be able to reach the 1000/1000 golden age in a decent time, less and i would reach it before i managed to finish chichen itza. Its kind of a balancing act, as you want the golden age to kick in abit before you get to arcaeology. This way you can prepare to get The hermitage fast, by making the prerequisite culture buildings.(or buy them)
After my fighting force was out i just spent the time growing my capitol and getting another great scientist for arcaeology. Actually In this game i didnt focus on culture accumulation at all until i reached my second golden age. I was just preparing for everything so i could build the culture improvement faster, and "explode" in a culture boom. The reason is that culture buildings and culture output from your city is rather low without consitution, and hermitage. It just doesnt seem worth it to make a temple early.
From here on it was just a matter of getting enough puppet cities and luxuries to keep myself around 0 empire happiness(getting below from time to time was ok aslong as i didnt got get below 10)
If i had too much happiness i conquered one city or two on your continent. If i was around 0, i just waited.
To get to christo asap I pumped out another 2 scientists, got one from the porcelain tower, and saved my oxford university. This way the same turn i invented
Military science, i could get straigt to
Biology -> Steam Power -> Electricity -> Telegraph.
Having managed to get a engineer out beforehand for chirsto it saved me quite some buildtime also.
I got to Telegraph at turn 197 - 1370AD
Took another 32 turns to complete the remaining policies and 11 turns to complete the utopia project(had 0.25 hammers too little to complete it in 10 turns..... QQ )
From turn ~120 -197 i was almost constantly in a golden age. This helped me greatly to pump out those extra hammers needed to make wonders faster.
1000/1000 golden age + 2 great generals + 3 artists + taj Mahal(from what i can remember)
Btw what a great thread. I have learned soo much from here about how i should approach this. Hopefully my second game will end well also so i can submit a valid game.
