Ever thought it was kind of weird that in civilization one leader survives for thousands of years? Well what if we made a feature where civilization leaders die over time maybe as a random event thats chances increase how ever long that leader was in power. When ever a leader died a new one was put into power which gave different benefits and disadvantages. Also when starting a game civs have traits instead if the leaders since right now there is no benefit of playing as a certain civ because they dont have a unique building or unit. Just an idea.
