Even if a city doesn't generate any

points for popping borders,
any city passively produces "tile culture" which influences the amounts of different cultures each tile has, which determines, in turn, the cultural composition of cities. The

points add to that value, but they are not equal nor are they the same thing from the game engine perspective.
Interesting. Seems like there is a lot more depth that I previously believed.
And I'm pretty sure Trade Route are also conducting

in some way, as I spotted Japanese Cultural influence on a few tiles in Spain (And I don't have any other explanation except for Trade Route as to how this could have happened).
If you want the gory details, this thread has them:
Please, have mercy ! This game is already hard enough for my brain as it is
Let me preface this with the fact that I in no way endorse running World Maps with revolutions on, simply because the number of free civil slots is minuscule, and after those run out, you only get barbarians.
I understand, and do think too, that "real" Civ are more interesting as Revolutions byproduct than "just" a Barbarian State. But still, if the choice is having the Revolution with subpar barbarian, or no Revolution at all, I still believe the Rev On makes for more interesting game.
As an exemple : in my current game, France wiped out Spain. With Rev Off, that would have been it.
But, having Rev On, a few decades later, France was involved in a gruesome war with another Civ, leading to instability on it's recently conquered spanish cities. They revolted, and Carlos V resurrected from the dead.
Can't really say that he will be a main opponent of that game, but still, seeing him back was a funny little thing that I enjoyed.
But I admit that the unending list of Civ on that map is sometime troublesome.
Secondly, if you're playing SVN, you're more or less crash-proof, regardless of how big the save gets, due to unpacked assets.
... For real ?
All those years, I believed that the Huge World Map was impossible to finish, and that it will always crash before Industrial at most.
And now you are telling me that, if I find the strengh in me to continue despite how long each turn is, I may be able to see a victory screen ?
... Man, I feel like a grumpy old man that just learned that Santa is, in fact, real, and coming by for a coffee this afternoon.
