I'm trying to roleplay how I deal with captured settlements, taking my lead from the fact that Rome relied upon a cycle of conquest and enslavement for much of its history...

- if it's a Roman settlement I only ever occupy, even if they've rebelled against me.
- if it's a Greek settlement I usually occupy, but occasionally enslave if the strategic situation is such that I have no option or if the settlement has rebelled against me or another Roman faction. I count Corinth as Greek even though it's held by the Macedonians at the beginning. This is just my attempt to emulate the Roman's admiration for many aspects of Greek culture.
- everybody else usually gets enslaved, unless they've rebelled against me or another Roman faction, in which case I usually exterminate them upon re-capture. I'll usually also exterminate 'problem' cultures... for example, if the Carthaginians have given the Scipii a lot of trouble, particularly if they've taken a Roman city. Revenge is a dish best eaten with lots of chilli sauce and a diet coke is my motto.
