Well i lost a lot of time cause i dowed rome, which made poland reallly dominant in the other continent, and they started to get a lot of culture.
This game was a huge battleground, bothharald and moroco wanted the poor boudica's death, harald kept harrasing utique but it even scary, the ranged frigates are just insane when they are ready around T150.
after the first peace treaty with harald i took my fleet to help city states and india to fight the bloodthirsty caesar.
liberated 2 city states, 2 indian cities and destroyed a couple of roman cities, which was a really bad idea, getting 2 more culture city states wastn worth the culture poland got from conquering the whole continent, just because i killed so many roman cities and units.
To get such an early win, i did get guilds going asap, rushed acoustic the printing and took all wonders, then beelined archeology(started with frigates to keep me safe and buff the prod) i did way too many archeologist, like 3 or 4 of them couldnt even get a relic cause all my slot were filled.
so around T 150-160 i had every single culture wonder exept partenon, aesthetic was finished around T 140, got a 45 turns long golden age thanks to chichen itza + 2nd natural GA thanks to insane early happinnes + aesthetic + taj mahal. a bit after the end of this one i bulbed a GArtist for another one when i won world fare(no more art slots so...), used a great writer to speed up the T3 tenet for the +34% culture from broadcast towers aswell.
Another mistake was to pick patronage opener, i should have finished ratio to get hotels faster. i also didnt delay a great musician that could have saved me some turns aswell (poped like 5-10 turns before hotels).
what helped a lot is the fact that i had like +150 gpt at turn 80ish ... bought every single cultural city state to avoid AI getting them, it gave me stupid amount of hapiness.
i had enough gold to buy all my buildings aswell, so all my prod went to archeologist and wonders.
wonders built :great lighthouse, oracle, petra, angor wat, chichen itza, sixtine, globe theater, ltop, forbien palace(super late for 1 more art slot xD), PT, uffizi, taj mahal, louvre, broadway, effeil tower.
