I once play Romaioi Barbaroi migration campaign into Pergamon, and Mytilene, roleplaying as Troy, but that time, I modify my EDB to get polybian hastati (light sword Infantry = Xippherai) and cammilan triarii (Heavy Hoplite), recruitable from all MIC, and I also made Mistophoroi Phalangitai recruitable too (and temporary remove them from da mercenary pools), it was somewhat fun challange to reconquer (and end up exterminating) Barbaropolis as the Romaioi Barbaroi (hey, in this state, they are Trojans), oh yeah, after taking Pergamon and Mytilene (by teleport), I FD all my Italian terriotry to Avernii.

A Trojan campaign, really awesome
