Considering the factions that are in Mount and Blade and Warband are based on medieval European and middle eastern cultures. The current factions are Swadia who are based on the Holy Roman Empire, Rhodoks based on the Northern Italian City States, The Nords on the Vikings and Saxons ,Vagiers on the Kievan Slavic Russians, Kherigits on the Mongols and Turkic people, and the Sarradins on the Islamic Middle Eastern Kingdoms. I am wondering for more factions based on Medieval Cultures that havn't been covered yet. Everything must be European/Mediterranean. There will be NO ORIENTAL CULTURES (other than the Kherigits) WHAT SO EVER.
Viable cultures that can be use can be Spanish, Moors (Arabs in Spain), English (Pretty much like swadia but with longbowmen instead of crossbows), Scots, Poles and Hungarians, Byzantines, Southern Italian City States, Italian Papal States and Norman Sicily. For I like the Empire of Trebizand for the name Byzantine based faction.
here is a politic map of the M&B2 map should be. Note it resembles a poorly drawn version of Europe and the Mediterranean area. It shows the starting location of the factions including the proposed factions. More faction names to the map will be added once they are decided.
