The twenty-faction limit is driving me crazy. If you could have another faction, who would it be? And if you had to get rid of a faction, who would it be?
Me, I'd love to have three Gallic factions (Arverni, Aedui, and Insubres), another Germanic faction (not sure who), Pergamum, the Saka, Axum, and lots more.
As for removing a faction, I'm not a huge fan of Illyria, and I occasionally wonder what would happen if we gave Sarmatia control of Arabia and Numidia and made them the world-wide horse raider faction.
What about you?
