You have made me a Evil Despot.
I tried your Ma Pyth with 3 order, 3 growth, 2 bad luck, 2 drain. It seemed wrong but works good. 140% taxes seemed the best trade off as pop flight seemed to kick in bad at 150. I was using Vestals under a Serpent Lord for patrols cause of speed and holy savings.
The extra money to kick in gladiators to take the edge off strong indies worked nice.
The army of 5 Hydras is a hot knife in butter. With the massive amounts of money I am thinking of fielding two or three more. Then condensing them into large armies backed by archers for other pretenders. It is a matter of choosing the right battles for them.
THE DOWN SIDE.
I did good for awhile. Then the attacks started. A Hero with 40+ knights hit my capital to end my unjust rule. I barely won thanks to patrols. Bogus took the province next to my capital. The knights not accepting loss hit my capital again. Some water Hero took the Sea of Woe. Three turns after my first city started to produce the Knights crushed it with a army of 46 HC's. I sent in 80 gladiators backed by two armies to end the siege.
Then it dawned on me. These are HEROS trying to free the people from a Evil Despot who has death squads patroling his lands to keep the people reduce to poverty by my ruinous taxes from rising up against me.
You made me George Bush.
