I've started a Migration campaign like Quirinius, although this one with my favourite faction Macedon. Its a rather small one, simply over to southern Italy, although it hit a snag. Not a bad one though. I emptied all my greek settlements and took Croton and Tarentum and wiped out the Brutiians. I tried giving away my settlements to Thrace, who didnt accept. The settlements just sat there for turns on end, completely empty, with no one attacking, making me 1000d per turn. So i eventually just started training units. So now i have greece AND southern italy, and a 100,000d war chest.
