Ok, so I tried Korea again and managed to push the science focus a bit more and won on turn 282, last time it was 320. Both on emperor.
This time I again had to keep a rather large army so neighbors didnt get any funny ideas but I built cargo ships much earlier so the economy was really good through out the game, stayed away from buildings I did not really need and only aimed for the wonders I thought would help me win and that I thought that I could get. Broodway and the Eiffel tower is nice and all but does not really generate any science.
Spent a lot of cash on CS to help with food and culture (and some units) and perhaps most importantly, happiness. Towards the end I had 8 cargo ships but 6 of them went between my 3 cities (size 24, 32 and 49 at turn 282).
Planted 3 GS around Seul, bulbed a couple in the mid game to get to Plastics quicker, also built Oxford during that beeline. Then I saved all the GS (4-5) until I reached Satellites and faith bought a GE to get the Hubble then bulbed all my GS.
There is of course a lot of things I could have done to get a quicker win but with Russia as closest neighbor and Germany not far away I had to spend cash to upgrade units, cash that could perhaps have been used to buy buildings (did manage to buy all the science buildings in Seul) instead of building them or RA´s (and spent the hammers on science instead). Could have scaled off some turns perhaps.
Managed to time Statue of liberty in time for the Worlds fair and then spent a lot of cash to ally as many culture CS as possible when I won it. That gave me a lot of social polices that helped a lot (finished patronage and got some extra from the freedom tree). Burnt 2 great artists for the extra production as well and saved a great writer until the 20 turns of double culture was over then burnt him as well.
Infact, only had 2 tourism, used every person for golden ages and extra culture and just deleted the musicians since I did not have any place to place the great work of arts.
And I was really aiming for a turn 280 win and could have gotten it but messed up the last 2 turns.
Don't use the beaker overflow thing, not intentionally anyway. I want to get the tech lead asap then just push forward toward a SV.
Edit: Managed to get a religion before I even spent a single hammer on a shrine. Was the first to meet two religious CS and also meet a 3rd that gave me 4 faith. But those 20 faith was just enough to get a pantheon and since I had 5 salt (two in capital, three in 3rd city) I went with the Earth mommy thing, then when I founded a religion I got Tithe (1 gold for every 4 followers) and food and happiness from temples and shrines) and first then I started building the religious buildings). Managed to get Hagia Sophia to enhance my religion.
Wonders I built was Oracle, Hanging Gardens, Hagia Sophia, Machu Picchu (late in the game, think I was the only one who had a mountain nearby), Notre Dame, Forbidden palace, Porcelain Tower (was the only one who had opened Rationalism), Statue of liberty, Hubble and then least but not last Sydney Opera house very late. Used a GE to build it to get a free SP to close Rationalism for a free tech.
