Dwarf Fortress

Dwarf Fortress is a single-player fantasy simulator. You can control a dwarven outpost or an adventurer in a randomly generated, persistent world. The world is procedurally generated with distinct civilizations spanning centuries of detailed history, multitude of towns, bodies of water, caves and regions with various wildlife. The world persists as long as you like, over many games, recording historical events and tracking changes.

Command your dwarves as they search for wealth in the mountain. Craft treasures and furniture from many materials and improve these objects with precious metals, jewels and more. Defend yourself against attacks from hostile civilizations, the wilderness, the depths, the dead and creatures of the night. Support the nobility as they make demands of your populace. Keep your dwarves happy and read their thoughts as they work and relax. Z coordinate allows you to dig out fortresses with multiple levels. Build towers or conquer the underworld. Build floodgates to divert water for farming or to drown your adversaries... and don't forget the magma! Surgery, sutures, splints, crutches and more: care for your wounded dwarves instead of leaving them to fend for themselves.
