I thought of something really cool to possibly add to the CBP in regards to events.
So, one concern about the CBP is that happiness below 0 is not nearly as big of a bad thing as it is on the main game. However, it is necessary that the penalties are not immediately too harsh because of the way the happiness system works.
So my idea is: Corruption Events. Corruption Events represent what happens when an empire is badly run. Authorities steal money from the coffers, and generally self-interest of the few gets in the way of the good of the people. They would all be bad, of course.
The way it would work is: every happiness below 0 will increase the chance of a corruption event happening, which pressures leaders to try to get rid of it so as to avoid them.
The best part is there would be probably little to no AI training required for this feature.
