Need some advice for how to manage economics & military in early eras (particularly classical & medieval). The latest game playing Persia on Prince level, I have been finding that no matter what I do, I cannot manage to have a positive bank account at all and have a decent military (meaning around 6-10 units, & a couple of workers). Every time I check with my military advisor, he keeps telling me all the surrounding civs are stronger than I am, and even when I maxed my trade caravans (2), built roads to all my cities (6), markets in my main cities (top 3), & oligarchy for free garrisons, I still cannot get out of the red! Can some of you explain how you manage to keep a decent military comparable to rival civs? I think I need to shoot for about 8-10 units to keep rivals civs from constantly attacking me (which kills my caravans & makes matters worse), but I can't seem to be able to even afford that, and the lost gold is killing my science. Any useful advice would be appreciated (or even workarounds if the mechanics are broken). Also, is anything about early economy/ early unit maintenance being address by the new patch (didn't see any notes regarding that)?
