well I have three campaigns...
Getai, Saka (India), and Sauromatae...

with the Sauromatae i am trying to expand from the Baltic all the way to the Caspian, and down around the Carthpatians, Black Sea, and Caucasus

but I'll try migrations with 'em too.... migrating to wealthier lands... hmm... GAUL! ITALIA! GREECE!
