I know the Roman Republic, and later Empire, was all about expanding the light of Rome to the rest of the brutal and cruel and dark world. However, as the game is confirmed having POPs and trade, I wonder if there'd be room for tall playstyles, not necessarily entirely peaceful, but for example having the taking of slaves from other nations, demanding tribute, so growing without actually having to expand owned territory too much, but instead developing what we already have. Maybe an extensive and varied vassalization system?
