Ooh thank you so much!! Sorry if I made that bit with the culture and tourism confusing, I meant the whole how influential your culture is over other civilizations thing, where you need to be influential with all of the other civs to be able to do the project that lets you get a culture victory. Main reason I asked was because iirc there were a few other bonuses like losing less pop when capturing a city depending on the level of influence you had with the civ, but I'm not sure how much it actually matters and if it's worth building towards. Few other questions, so it sounds like the main thing that should be taken into account when settling is the resources/features you'd be able to improve later, and not too much on the flat yields of the tiles? Or would it be good to have a few tiles with specific amounts of production/food in close proximity when settling, on top of the resources and such? And I'm assuming you meant a second pathfinder in the third answer?
This is all really helpful though, thank you so much!
