I have to agree with mlp071, the koinon are very over powered, in every game I have played they have battered Macedon in about 10-20 years, unless I pump macedon full of money or directly intervene (Macedon still have a hard time even with that help).

Yeah mods need to be taken into account and the fact that people aid their preferred factions with money boosts. I am surprised and I cannot believe that the screenshots in the AI progression threads are showing natural Macedon expansion where macedon is a powerhouse. It cannae be true. The only time i have seen macedon naturally beat the Koinon was when they did their rare cockroach maneuver. With the victory conditions mod I set macedon's target areas as all of greece, and made Koinon's targets just southern greece. The chremonidian war has played out very accurately, with Athens fallen and only sparta left.
