I'd like to make a few suggestions for your new mod:
1. Map should focus heavily on pannonia, illyria, the Balkans, hungary and dacia, and part of the black sea.
2. There should be multiple types of Goths - Grethungi, Radagasian, and Tervingi, maybe more
3. Suebi, Hasdingi vandals, Silingi vandals, Alani, Sarmatae, Heruli, Scirii, Rugi should all be present as factions.
Just a few tips.
