City-State Diplomacy Mod (CSD) for Brave New World

City-State Diplomacy Mod (CSD) is a complete overhaul of the city-state diplomacy system. It eliminates the importance of the 'Gifts of Gold' mechanic and introduces a new, unit-based system of influence.

Players are now encouraged to build and use diplomatic units and/or complete city-state quests if they want to earn influence. Because diplomacy now requires production, time and energy, players must actively and consciously strive to maintain good relations with neighboring city-states. Furthermore, diplomatic units, being defenseless, are liable to capture or destruction if sent too far from safety, thus long-distance diplomacy now utilizes a risk-reward system. The AI has been trained to utilize this system, so do not be surprised to see diplomatic units from many different civilizations criss-crossing the world in search of influence!

- Includes 4 diplomatic unit types (unlocked in progression), each with marginally better influence generation.
- Includes 1 new great person (Great Diplomat), 1 new specialist (Civil Servant), and 1 new Improvement (Embassy).
- Includes 2 buildings, 7 national wonders and 6 world wonders, each with unique promotions and bonuses for city-state diplomacy.
- Includes 7 new World Congress Resolutions, and all existing Resolutions have been revamped.
- Includes 10 new City-State quests.
- Includes a new resource, Paper, used for diplomatic units.
- Modified policy tree to incorporate CSD buildings.
- Overhauled AI (based on a modified .dll) for diplomatic units to encourage competition for city-state control.
- AI trained to intelligently spend gold on units and buildings, to more intelligently vote in the World Congress, and to offer more dynamic diplomatic relations.

This mod has been edited and tweaked for years for maximum compatibility with other mods and for quality compared to the vanilla game. That said, incompatibilities do exist. This mod will not work with other .dll mods, for example. When in doubt, ask me below or on the mod's civfanatics page:

Instructions: The settings for this mod, including tweaks to gold gifts, the Patronage tree, Sweden, and so on, can be modified in the mod's included Options.sql file (open with TextEdit). When you open this file, you will see sections that look like this:
Gold Gifting and Gold-Related Quests with City-States On/Off
1 = Gold Gifts Enabled
2 = Gold Gifts Disabled (Default)


To re-enable gold gifts, change 'GIFT_OPTION', 2 to 'GIFT_OPTION', 1
This explanation applies to all settings- just set the integer to the desired value and save the file.

If you are using Enhanced User Interface, delete the CityView.lua file from the following folder:
C:\Users\~\Documents\My Games\Sid Meier's Civilization 5\MODS\City-State Diplomacy Mod (CSD) for Brave New World (v 20)\Assets\UI\InGame\CityView

Note: CSD - BNW v.26 has a modified .dll. For an older version of this mod without a modified .dll, please look here:

Same problem as OmegaMole - GD spam is an absolute game-killer. The worst thing about them is that they make whole areas of the map inaccessible unless you declare war on their owner and kill the offending GDs. The mod is otherwise good but this completely ruins it for me, to the point where I won't use it in future games. I guess you're probably not tweaking stuff on it anymore but I'd appreciate it if you (or anyone else) could point me at a way to fix it in the mod files so I can go on using it

A little update on the Great Diplomat (GD) spam. As I have seen all Civs spam GD which makes the game unplayable. The AI does not disband the diplomat units and therefore has soon about a dozen and more of GD without any use on the map. They cripple the AI financally an block the whole map. Also while the spaming stopped during midgame for about 50 turns it started again and raised from 1 to 5 GD each turn over time. So as long as this isn`t fixed, this mod is breaking the game and cannot be recommended. It is strange that this problem appears now, because it didn`t before I reinstalled the game and the mod.

@Gazebo I Have a simmilar problem as Revan_Avernus. But in my case I AM spamming Great Diplomats. Since I invented writing (I guess) the game gives me a great Diplomat EVERY single round. That unbalances the game and it is annoying as hell that I have to disband the diplomats every round. Maybe you could do something about that? That would be great because I love this mod and don`t want to play without it anymore. Great idea and work!

It´s OK mod. I just wish that the World Council changes would be a separate mod, because I don't like the diplomat unit addition at all. AI keeps spamming 3-5 diplo units constantly to my Ally City States and in every WC meeting AI´s mostly propose "Enforce Decolonization" to CS´s under my influence. I have to keep churning out diplo units from my major cities and can't focus on anything else. Also when I vote against these decolonization- proposals, my ally leaders start to dislike me.
Any way to remove diplo-units and keep the WC wonders and new proposals?

Can you make an EE compatible version? The only two conflicts (duplicates really) I can see is the Summer Palace and Crystal Palace existing separately in both mods, but it's still pretty cheesey to potentially have 2 of the same wonder that do separate things.
