I suppose you could flip independent cities as well, but maybe not all of them.
I would say a celtic galatian city around ~270BC in Capaddocia.
All independents in Greece, Thrace (if necessary) and Asia, as an emergency measure to make the game possible in case of Roman failure.
Yeah, pretty much that spot on the mountain in the corner of Cappadocia (Ankyra). It could be slightly more east but that spot minimizes overlap with the other cities.
The city (Ancyra) grew significantly in size and importance under the Phrygians starting around 1000 BC, and experienced a large expansion following the mass migration from Gordion, (the capital of Phrygia), after an earthquake which severely damaged that city around that time. In Phrygian tradition, King Midas was venerated as the founder of Ancyra.
that stupid bug about vacating the capital! hmmmm...
