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:

Civ 5 better diplomacy is not compatible with this mod, as they are both DLL mods. Use the Community Patch Project:

No, windows only.
Pothockets Jul 9 @ 7:33pm 
Is this made to work on platforms other than windows? Im currently on steamOS and this mod crashes immediately after configuring game data.

You've got a mod conflict with another mod.

[Bug] Really like this mod, but have run into some issues.
1) When I DoW a City-State, I cannot make peace in the CS diplomacy screen. Is that a bug?
2) Whenever a Civilization becomes allied with a CS and it declares war on me, the influence bar does not drop to -60. Instead, a weird mishmash of icons on the CS occurs (will get screenshot). Also when this happens (every time), there is a delay in the city UI - when I annex a puppeted city it still has the "puppet" icon on it, for example.
3) The Great Works screen on the "Culture" UI doesn't show Great Works slots, so theming bonuses are impossible to get.
