It's been a while since I played them, but I do remember Surrectum has Areas of Recruitment - for instance, if you recruit a legion in Italy, it will be a certain legion, while in another province it would be from a different legion.

And If I remember correctly, they both remove the Julii, Brutii and Scipii families in favour of a single, unified Roman Faction - something I thought was a lot better.
