Start with Governor
Governor becomes available with first civic (Code of Laws).
Why would you want that?
Avert loyalty issues in capital:
Early capital flips are a common issue in hyper-dense maps – either pre-made ones or those generated for "more players" setups. Granting each civilization an early governor safeguards the capital.
Flexible governor strategy:
Early promotions (and, thus, second tier governor capabilities) become a viable alternative during ancient/classical age, as governor grants are more plentiful.
