Heyman
Yeah, found my first time pretty hard too.. here's how I did it & got a steady supply of that precious gold! (It ain't gold it's denarii, but it's similiar lol :p)
1. You should disband several units since roman strength rely on the discipline in their lines, usually they can stand their ground against much larger forces - although watch out when you're fighting in the east - bring lots of cavalry...
2. Create trading ports, make trade agreements, build farms (good investment), build roads - essentially everything that gives a profit margin.
3. De-construct buildings if you're REALLY low on money and need it BADLY.
4. If you want a forced diplomacy integrated let me know, I'll post the files needed here since it's very easy to add. (I use it to keep factions alive, giving them regions etc... basically keeping every faction about the same size in number of regions, since having more factions at end-game is MUCH more satisfying
- I don't use it for personal gains since the game is much better when playing without cheats).
5. Try to let cities with too high a population to make a profit rebel against you, and take the city back, then eXterminate the population/enslave them (destroy the barracks etc though otherwise they'll spawn a well armed rebel army in the city).
6. Try to post low-cost units in cities to guard - move heavy upkeep units to the front.
7. This is one is for battle
: Try to take the best ground on the campaign map if you know you're going to be attacked (like a hill, since you can pound them with your archers sooner, tires the enemy & is better for your infantry to fight on - don't attack with cavalry against the rear from behind since that has little effect).'
8. For the rest: Enjoy the game, and show 'em barbarians who is the master!
