and still nobady remember whats probably the most obvious faction of all

the schytians of mikra schytia, altough they where being pushed aside by the sauromatae they where far from dead since they only got conquered by 110 bc. (by a pontiac king) a mixed schytian hellenic faction that could work like the saka on the west with a mix of hoplites and horse archers and with the amazing crimean heavy archer to defend it´s walls from the getic the sauromatae and the persian sucessors (hay or pontos)

they would be a buffer beteween the getai and the sauromatae and there´s 4 possible city´s for them (2 in crimea) olbia (capital? altough it wasn´t conquered by 272bc and was a greek city i believe) and that one that normally gets stormed by the sauromatae in the sea of azov

for victory conditions they could possibly have to emulate their massive invasions of the 7th century bc (?) wich enabled the persians to press the advantage and overthrow the medians and the assirians (?)

there´s some evidence that in the sea of azov there was a schytian city that had the hability to house over 1m people (and i know it´s from wikipedia so not so reliable but if it could impress the greek authors maybe it´s worth a chance at fighting back the sauromatae and give the getae a run for their money at the start)

seems the most obvious of all (after the boii and the belgae)

anyway just my 2cents for a dream come true of a steppe faction with a greek economic development an schytian-hellenic faction
