Just wanted to raise my idea on improving game immersion specially to those who are medieval gamers. In Sultan Ascend DLC, we have unit models for the crusaders: Templars, Hospitaller and Teutonic Knights.
Imagine implementing this on European CIVS? Imagine using the unit models for Saladin and other campaign sultanate units/leaders.
It would be better a DLC with Templars variants civs that includes these kind of units. But I wouldn’t put them as the standard units for the actual civs.
