- Imperial needs the heir to be younger. It's silly that a ruler is 80 and their heir is 78. That's a pretty young time for conception.
- Dictatorship needs more than just empire sprawl -10% (That's what, at 200 sprawl 1 admin office?) They should get something that matters, like imperial does.
- Democracy. Cheaper leader cost/upkeep as you lose them SO often.
- Oligarchs seem fine. +15% unity is strong.
- Achieving these should grant a % unit rather than a flat. amount This lessens snowball while granting a nice curve into the late game. Perhaps unity based off pop and different system colonies.
- These should change automatically after a period of time or a player can influence these with influence.
