I've been playing this mod for a week or so and am in 496 ab urbe condito which is 258 bc. I use a guide to play as historically accurate as possible as the Romans. This means I rule italian peninsula and Messana. First Punic war is raging.
My point: I have been building like crazy and can use normal diplomay (not force) because of the enormous amount of money. I play on Hard Campaign difficulty but at this moment all building slots are full and my treasury is still 136.000 (!!!)
I spend as much as I like because every turn some 30.000 is added.

Is this normal? Historical accurate that the Romans were loaded at that time?

Is the balance of this mod not proper?

...just wondering...
