For a while I've been thinking of alternate history mod in which Alexander the Great does not die of sickness and you help him conquer the rest of the known world, or you play as another faction a try to stay independent. I'm not the greatest modder however so I was hopeing a larger team (like Surrectum or Europa Barbarium) could provid some assistance. I think this would work best for BI as I plan to include hordes and emmergant factions.
Faction could include:
The Macedonian Empire
Chandraguptian Empire (India)
Manga Grecia (a league of greek cities including Syracruse and Tarentum)
The Etruscan league
Carthage
Saba (or another arabian tribe)
Sarmatia
The Saminites
Nervi
Independent Greek cities
Illyria
The Geto-Thracians
Cappadocia(Mabey)
Rome
The Celt-Iberians
The Kushite Empire (A Nubian Faction)
The Dahean Confederation
The Chatti
False DIodachi (Like Roman Rebels in BI)
