Getai are fine, they have some of the best skirmishers, which can also hold a line for some time, the best pseudo phalanx, horse archers, good cavalry for all purposes, shock infantry with high lethality and shock infantry with AP, plus they can get hold of righ mines fairly early in the game. major downside are thier enemies which are mostly phalanx or horse archer based :(

imho they have the second most diverse unit roster in the game(after Baktria)

and Victory conditions, Pff, whats that supposed to mean? it's not like the game stopes when you win. most eastern factions have to aquire more land for thier VC than western civs yet this is mostly due to higher settlement density in the west. afterall you can expand in which direction you like nothing holds a sweboz player from conquering italy or the balcan. afterall the larger the VC area the longer you "have to" play the campaign and tbh, even with sweboz or sauromatae you'll swimm in cash at a certain point and from then on every game becomes kind of boring :(.
