Nice description of your campaign. It's surprising how quickly things can turn sour if you don't watch them, particularly on the economic side. I've had to abandon more than one TW campaign because of running my economy into the ground, sometimes despite winning every single battle.

Personally I find creating a functioning and stable economy to be the hardest part of a campaign. Generally I find the best rule is either to begin by furiously attacking, raiding, and conquering everything around you ASAP or beginning slowly, making sure to make every koku/florin/denarius count (build things like roads, docks and trade) and cautiously building up and expanding, always with an eye to what will make the most money. Then, once you're consistently "in the black" (making a profit) you can think about world domination. Which one works best depends on the location and unit makeup of the faction you're playing.

Anyone else got any economy macrostrategies?
