I started selling maps the very first turn to create a nest egg to fund the expedition, since I knew my new homeland would require a lot of work to get up and running. I was able to get several juicy regular tribute deals that really pumped me up on top of the wealthy Selucid cities (I'm not playing TR).

That said, I'm now back down to around 10,000 dinarii and have finally stabilized the hemorrhaging of my treasury. I suffered massive drain after I took Londinium by creating large numbers of Phalanx Pikemen. I've now taken over all of Gaulic France and it has only been with their already sizeable cities that I have been able to get my finances into the black for the first time since abandoning my starting position.
