Thanks for the reply.

After starting over a few more times I finally managed to get the finances under control. It seems to work better with Julia instead of Junia, because it's easier to get trade routes with a lot more civs.

I have a few more questions.
1) Do ya'll try to complete all the objectives for each chapter mission for the bonus cash from them?
2) Is it better to ignore the most of the bonus objectives and just complete the main chapter mission? In other words, will I make more money from just conquering my way across the globe taking the provinces I want and expanding my armies as I go instead of trying to complete all the objectives first?
3)After reading some other threads I've started just razing every settlement after taking out the Etruscan League (I occupied theirs because they already had roman buildings). Do ya'll do this too, or are there times where it's better to occupy? Is there ever a good reason to loot a settlement since it just damages all the buildings, but doesn't give enough cash to pay for the repairs/conversions, has the highest unrest from the initial, overtime and all the added slaves?
4) Is there really any point to having fleets with more than just the admiral and maybe a unit or two set to patrol?
