Not so: the Greeks wrote that the Romans were ignorant uncultured barbarians; the Romans wrote that the Greeks were effete barbarians; seeing as how Phoenician culture in the Western Mediterranean was older than either of them, I bet that the Carthaginians thought that both the Romans and Greeks were noveau-barbarians; the Romans definitely thought that the Carthaginians were barbarians; the Macedonian Successor Kingdoms were barbarians anyway according to "real" Greeks; the oldest of all world civilizations in Egypt and Mesopotamia surely regarded their Macedonian overlords as inconvenient barbarians; gods know that the various peoples of northwestern Europe were all barbarians to the literate cultures of the Mediterranean, and what they thought of the Romans etc. is largely unrecorded but I bet that "barbarian" was high on the list; and the various horse peoples of the Eurasian steppes largely thought that anyone else was barely even human.

Every single faction in Europa Barbarorum is in fact a Barbarian faction, depending on who you ask. That's the point of the name, eh?
