Vanilla/G&K City-State Diplomacy Mod (CSD)

- Design Philosophy -
This mod is a complete overhaul of the city-state diplomacy system. It reduces the importance of the 'Gifts of Gold' 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!

- This Mod Includes -

This mod includes 4 new diplomatic units, two new diplomacy-centric buildings, two new national wonders, three world wonders, a modified Patronage tree and a modification of the AI's city-state diplomacy mechanic. See the spoiler below for more details.
