Vuk, it may be a mistake to put yourself first when you are just starting your go in the Thracian campaign. I would let UltraWar go first. Doing a PBM is more time consuming than you may imagine. (I personally am relieved you got the Thracian one going because I don't think I could handle it and the Will of the Senate at the moment. )

But if you do want to take both PBMs simultaneously, I would suggest you devote your time to Parthia first, not Thrace. Going first normally means things go quickly (because there are few towns and troops). By contrast, with Thace, Severous seems to have carved out a pretty big empire to manage.

Plus it would be good to get this one going while people are interested and, as I said, I definitely don't mind waiting a while for Thrace.
