Provinciae Romanae

[Maion Maroneios]

Achaea and Macedonia (which province is Demetrias in?)

Neither. Demetrias is the capital city of the province named Thessalia. Achaia has Korinthos as its capital, while Makedonia has Pella.

I think Demetrias is in the macedonia province, can't help you on the rest though. You'll need to look through the export_descr_ancillaries file for that.

edit: On second thought,

It isn't. Except if things are different for the Roman province system?

Well, to the Romans, those pesky Pellans were never fit to rule, so they keep demetrios as the capital. The EB team represented this quite well. :)

Ok you're forcing me to get my little devil out again, but I'm not falling for it. Not. Seriously.

well, Barbaropolis was unruly, but easy to conquer. So the Basileus of the fatherland decided to let them live and cull them once every few years...

Why is it that the behaviour of the fans of the following factions are:

Macedonia hates Romans
Romans hate Barbarians and Macedonia
Barbarians hate Romans and each other
KH stays neutral unless supporting Macedonia
few people like Epeiros
