Management is still possible. But since most of your resources will be focused on military concerns, troop recruitment, military buildings, agent recruitment, fast expansion, and so forth, the economic side of the game will not happen until you've taken about a third of the map or so, and then only for purely selfish gains like building ports for a quick trade boost.

Sicily isn't a good faction for this. They will not be able to crusade through many excommunicated Catholic factions, a key element to rolling up the map.

I recommend England or France, as I've personally completed the challenge with them. However, I feel it is possible to do so with the Holy Roman empire, Venice, Spain, Portugal, Milan, Poland, and Hungary. Maybe Denmark.

The key is owning all of central Europe very quickly, as crusades to the corners of the map take care of the rest. I found the best way to do so was a mix of ending crusades with 4 or 5 stacks inside Catholic territories, then massively backstabbing them, or crusading and abandoning the crusade after capturing a settlement, thus turning all those troops into non-crusading units for a while.

You will need to be fielding roughly 15 stacks ASAP. By the end of the game, you should have at least 25 offensive stacks, and of course militias keeping order at home.

You will go into debt, but you must conquer your way out of it. Troops are more valuable than florins.
