Could you make this mod so its an IA for Portugal too? Because with IA this only affects the Italians and Portugal's IA lacks walls so the Portuguese faction is stuck with ridiculously unmatchin white walls.
The Spanish could also use the this stone wall since they too lack a proper stone to match with their IA architecture, however they do have a very fitting fortified walls.

The Fortified Walls are already included in Catbarf's Mediterranean IA mods for Spanish & Portuguese, but I could include Portuguese Support in this mod.

Really nice walls. These complement the stone wall upgrade in a much more pleasing way and feels more "bulky" than the original graphic in a good way. :-) Any chance of seing IA versions of the other mediterranean civs (Byzantines. Spanish, Portugese)?
