Morale & Siege: New Warfare Mechanics

This mod expands the combat experience in Civilization VI through a new UI and new gameplay mechanics. It introduces the concepts of unit morale and city morale (in the form of siege duration), aiming to make unit combat less homogeneous and to provide additional advantages for long-term sieges. In military history, brilliant battles are not only about numbers, but also about morale. Liu Xiu defeated 400,000 troops with only tens of thousands at Kunyang, picking them off one by one. Li Shimin won at Qianshuiyuan and then at Bai Bi, waiting for the enemy to grow weary before launching decisive strikes — sometimes even ending a country in a single campaign. Napoleon’s Italian campaign saw him outmaneuver a larger force over a year, turning the tide — not just through brilliant tactics, but also through the shifting momentum of morale. Yet in Civilization VI, battles remain isolated. Tactical victories rarely translate into long-term strategic gains, often turning into a simple contest of strength. Nowhere is this more evident than in siege warfare: until your ranged units are strong and numerous enough, cities become an impassable wall — a frustrating barrier to any tactical maneuvering. The Morale & Siege mod aims to change this by introducing new dimensions to combat: the concept of Unit Morale, and the concept of Siege Duration for cities. These new mechanics are supported by a new UI system, better integrating them into the overall combat experience. This mod adds an additional morale bar for units, displayed alongside the health bar. By default, the morale bar is hidden when a unit's morale is at 0 (similar to how the health bar works). The bar's color gradually changes from deep blue (at +10 morale) to white (at -10 morale). Morale changes are triggered by the following events: When a unit deals more damage than it receives in a melee attack, its morale increases by +1. When a unit is killed, all units within two tiles of the killer on the same side gain +1 mora
