Serious campaigns as Romani, Casse, Sweboz, Baktria, Saka-Rauka, Hayasdan, Epeiros, KH and Sauromatae.
Romani are an obvious choice (though not my first one) and I just had to test the Neigh-Impossible ones. I really enjoyed Saka-Rauka, and so had to try their easier version the Sauro´s. I´ve always liked isolated nations, so Casse fited me well, and so did Sweboz. Baktria I don´t even know why I tried.
Only won campaigns as Baktria, KH, Romani and Sweboz. Damn close as Casse, but stuff and then 1.1 got in the way.
