I spent a lot of last year hunting for exactly this kind of book, and my absolute standout is 'Divine Dungeon' by Dakota Krout. It nails the blend of fantasy world-building with that satisfying, almost spreadsheety management layer. The core, Cal, isn't just a passive location; he's actively researching runes, evolving his mobs, and budgeting his mana like a fantasy CFO. It's the foundational text for a reason.
The strategy really kicks in when adventurers show up. You're constantly weighing offense vs. defense, like whether to invest in a nasty trap corridor or spend that mana cultivating a rare herb garden to attract different classes of delvers. Later books get into territory management and even dungeon politics, which scratches that grand strategy itch. For a pure management fix, 'Dungeon Crafting' focuses more on the artisan side, which is a nice twist on the formula.
