In Rome, trade is king. Get your trade up, especially sea trade, and capture rhodes asap, as well as the greek and macedonian peninsulas. That'll fix things.

I once had 99k in the bank, but my army got so big it ate it up in 5!!!! turns, until i was negative and sending suicide assaults to get rid of men ;)

Reminds me of a time in mtw when i got a rebellion in my favor and had to disband 21 units of peasents...
