How culture x tourism works?
I have +1100 culture per turn and China AI has +600 tourism (will all %) and china is rising influence over me.
Why China 600 tourism is better than my 1100 culture every turn?
There is number of cities or something like that or another thing that changes the ratio?
tourism is your offence---its like a sword
Culture is your defense---like a shield
you should see this in your "culture overview"
there is a list of all civ who are in your current game and there is a violet bar and white bar on each of them. like i said above tourism is your offence and Culture is defense.
if you could see the white bar is my tourism and the violet bar is Polish Culture their defense against my tourism i already got 75% when i got 100% i would be influential on them,and if that would happen its like i conquered them culturally.
your main goal if you want to conquer a civ culturally or becoming influential to them is to create a large amount of tourism. And also culture so you would not be get conquered by other civs. The best way to create alsrge amount of Tourism while creating culture also is by digging most of Artifacts in the game.
Another; The civ who has the less culture per turn, the faster you will conquer them like Poland in my game(he got only 1 city in my game). but civs like Russia and Germany in my game who got large Culture per turn, it might take time before you became influential to them.
P.S.
about the Ratio,
If you are open border to that civ you will create +25% more tourism or Speed towards becoming influential
If you share the same religion to that civ you will create +25% more tourism or Speed towards becoming influential
If you share the same Ideology to that civ you will create +25% more tourism or Speed towards becoming influential
If you have diplomats to that civ you will create +25% more tourism or Speed towards becoming influential
If you have trade routes to that civ you will create +25% more tourism or Speed towards becoming influential
not sure about the 25%, if what that means, its either +25% more tourism or +25% faster towards becoming influential
