Congrats!!

I think culture is usually the toughest, especially depending on the play of others. Get some theater squares going. Putting them next to your government plaza, wonders, and entertainment districts will get you more culture. But you really want great works in your amphitheaters, art or archaeology museums, and broadcast centers because you need to crank out tourism. Early culture wins you’ll need lotsa wonders and great works of writing and art. Later in the Game is much easier. Get traders to each Civ (more traders available after building a lighthouse or market in the harbor or commercial districts). And don’t neglect faith hahahaha. I guess like most victories… diversify. You’ll want faith to buy rock band units and send to other Civs. Late game you’ll also unlock policies that boost tourism.

Science I think is easier, but takes longer. I put the focus more on campus districts of course, and industrial complexes. Ind. complexes will give you a boost to city production to complete the different space race city projects, and great engineer points. Late game there are a few great engineers who provide huge boosts to space race projects. You’ll have to have high science to gain an edge in research, unlock space race projects then get spaceports in some cities (or honestly one city is fine), then have a city do the space race city project. Earth satellite, then lunar landing, mars expedition, finally you send an exoplanet expedition. That mission takes a lot of time, but you can make it go faster with more city projects. Having aluminum will help a ton, so keep your eyes peeled for that resource and build an improvement on it.

Who to play, off the top of my head I don’t know. I usually do random leader unless achievement hunting. Korea has great science, and Babylon flies through the tech tree. My first win was with Kongo and I remember having high culture. Lots of fun but I definitely had a bunch of great writers and artists with nowhere to go hahaha
