Hi everyone, I´m here to give an idea of a very simple mod. Although it is more or less historical that at start date Corinth belonged to Macedon (due to the old Corinth league in Philip II of Macedon´s times), it is true that it actually was like Phrygia in Athens, it was an ocupation with a garrison in the Acropolis, observing all the stuff around.
For this reason, as Corinth is one of the most important polis in Ancient Greece, I think Corinth should exist as a playable faction. Of course, it should exist being a Macedon´s Tributary state or something, like Athens with antigonids, so the player can reach the independence with Corinth and try to form a Corinthian golden age (who knows).
that´s all. Bye!
