AI has a strange way to choose this goverment.Before Fascism,Communism played the same role,when a civ enters a war after some turns it changes it's goverment to Fascism.But this isn't exaclty correct,i mean it doesn't mean that every nation under Democracy,Republic or whatever has to become a Fascist nation when war is declared,people react to war depending on what caused it.In the game thow Fascism isn't the choise of AI for specific periods of time or strategic achievements,but it uses it each and every time that war lasts for a longer period.I would like to see AI uses the diferent goverments depending on it's strategy and not as an equation of a program.
