Stronghold

Stronghold Crusader is a very good game, and the castle economy is particularly enjoyable, as you need to think before building, but it's not too complicated. I also really liked that the workers aren't just background elements; they're present and can be targeted. You can build the castle to any size (within reasonable limits), any design, and however you like. But there are also some drawbacks, as in any other game: the AI's intelligence in battles leaves something to be desired, and there's no option to build units in formations. And I forgot to mention the ability to lower walls for a better view. Overall, I really liked the game, but they went overboard with the graphics in the second part, and my little "separator" can't handle it after a few years, especially when there are a lot of people.
