Tactics for the Stronghold.

I build Orcs to take out Dwarven Mines and Crypts – and then some random hero shows up. (20 Orcs and a couple of Goblins). Meanwhile, my main hero is wandering around with Birds and Ogres, giving resources to some neutral creatures. And I end up with two fairly strong heroes who quickly explore the map and gather resources. By the end of the second week, I've almost completely conquered the castle. And I don't have any money problems. :-) at 200% difficulty.
