I might just be counting wrong, but the map doesn't look like too many provinces, I was guessing 4 African, 9 Italian, 3 Sicilian, 3 Islands, 10 Greek, 7 Spanish for a total of 36?, and making the remaining 14 provinces could mean you must destroy a faction.

I also as I pointed out propose that the quality difference between Marian and pre-Marian soldiers be drastically reduced, and the area of recruitment also be drastically reduced although it should still be higher compared to Polybian and Camillan.
