"Even the rest of the nations of the world which were not subject to the imperial sway were sensible of its grandeur, and looked with reverence to the Roman people, the great conqueror of nations. Thus even Scythians and Sarmatians sent envoys to seek the friendship of Rome. Nay, the Seres came likewise, and the Indians who dwelt beneath the vertical sun, bringing presents of precious stones and pearls and elephants, but thinking all of less moment than the vastness of the journey which they had undertaken,
and which they said had occupied four years. In truth it needed but to look at their complexion to see that they were people of another world than ours."​

A: You disabled Event System.

Will the AI be able to account for the new CS bonuses? Like will Shaka be more likely to want to ally Kabul than Brussels?
This is on top of normal ally bonuses, right? Anyway, I love it, more diversity is always awesome.

Merry Christmas to everyone ;)

And if you need ideas:
Sydney or Melbourne - -X% crime reduction
Wellington - double national wonders yield
Cape Town +50% trade range
Florence - +2 culture from marble, stone and artist, musician and writer specialist
Genoa - +10% trade routes yield
Kiev - +1 prod and faith from pastures, each horse resource produces additional horse;
Prague - -X% religious unrest

Sadly no, but Civ 6 doesn't even have that AI flavoring. Vox Populi AI tends to favor the city-states that are closer in order to close in on the votes and bonuses anyway for it to matter. (Which is why all the bonuses should correspond somewhat to their generic ally bonuses)

The ai favor cs which give him influence quest, which are friendly, which are near, which have a resource it lack, and which are good for his strategic victory(ies): it will choose military civ more if he pursue a world conquest strategy. So, to allow AI to make sound choice, the unique ability should be in line with the 'type' of the CS.

diplomatic victory: want all cs
conquest victory: want military ones
cultural victory: cultural & religious ones
spaceship victory: maritime & mercantile.

If you think its not enough, we can add a flavor column to the CS table and use it to bend AI a bit more, this change is easy.

edit: and we can add a lua callback to allow lua code to change weight in the AI CS selection.

Kathmandu - +2food and culture from mountains + ability to build mines on mountains, whenever at war with other CS or civ (balance), drops alliance to friend status;
Lhasa - provides ability to build Potala Palace unique World Wonder (+5f, +5c, +20% war weariness (yes, it increses ww)), when ally status is dropped, whole project hammers are lost/converted to gold;
Mbanza Kongo - +20% cs in jungle/forest;
Milan - GP/reneissance related bonus? +1c/f from great works?
Monaco - gold/tax evasion related? :)
Ormus - triple sea trade routes religgious pressure, gain gold from missionary religion spread;

We can still add something to spies.

Problem with +x on tiles means they are fairly poor late game, unless we make some kind of scaling with era.

If we could get the AI to properly take the diverse benefits into consideration, I'd be all for it, it sounds great!
Votes won in a majority. Development will be made for the new year!

How is this project coming along?
Terrible since a [Internet Company] is "temporarily" suspending me back and forward on certain days and it's hard to work when you have no internet, but the progress is still moving good. For example...

Now, I just need the main framework to be finished. (Making sure the city-states alliance aren't glitchy due to inconsistent alliance such as a sphere of influence when your influence with the city-state is below the minimum threshold of an alliance and the likes of it)

Update 2: Main framework has been finished. Only a few unique abilities needs to be finished and we are good to go! Edit: Also a few bug fixes involving World Resolutions and we should be good to go!
Balance Changes:
  • Friendly Threshold increased from 30 to 40.
  • Allies Threshold increased from 60 to 100.
  • Great Diplomat Scaling On Era increased from 10 to 25
  • Pledge of Protection's Resting Point increased from 5 to 15.

Why did you change the thresholds and whatnot?

Probably to compensate for the additional bonuses of alliance. And probably to increase the role of other aspects in City-State Diplomacy.
Is this the compatible implementation of Sukritact's Suzerainty?
Is this the compatible implementation of Sukritact's Suzerainty?
No, it's different since some of Suzeranity's bonuses aren't AI-friendly. As you noticed, there's not many unique features for the sake of saving the AIs. it's also not a compatible implementation because it doesn't override and delete every city-states.

Also he's the lucky one because I know for sure Sukritact's Suzeranity will break on CSD's Sphere of Influences and Open Doors Resolution which I'm trying to do some loops around right now.

What about to give militaristic city states more military themed traits when allies ? Such as bonus exp,unique promotions,healing,movement etc.
