I am in the middle of a second attempt at this one. It sort of clicked a few hours in and I began enjoying it, but now it's a dull slog. You take over a fort to the west, south, and east. Clear out mines in the west, south, and east. Then take over a second group of forts further west, south, and east. Then clear out more mines further west, south, and east.
There is a massive disconnect in the story the game is trying to tell, and what you actually do in the game. The game makes a big deal about how you are a prince of the most powerful kingdom in the world, yet you spend the entire game doing everything yourself. This makes the fort building feel ridiculous, as the entire continent is being conquered battle by battle by you and three other guys with bows, while the massive army you are supposed to be commanding hangs out in your seven giant forts spread across the land.
