Doing the first part of my AAR gave me some idea as it exists already in some games.
Can you add some random events who will affect your Leader and people capacity...
Example 1: There is an eclipse, the people trust that you're responsible : Less production during next 24 hours.
Example 2: The god of wind, Huracan is pushing your troops behind their back and make them move faster home....
These event and example (i have some more in mind if Devs are interested)
We need to be careful to use it no more than once or two per week but this can add some fun.
What do you think about it ?
Cheers...
