I'd be interested to see how Seleucid would be implemented as playable. The current version has some pretty decent starting territory of its own, plus something like 6-8 satrapies covering from Mesopotamia to the eastern edge of the map.

This seems like a rather OP start, even for an "Easy initial challenge" like Rome or Egypt. They must have some sort of huge drawback that is not apparent to me...or one would have to be added when it goes playable. All just idle conjecture on my part...anyone out there have more insight?
