http://www.bay12games.com/dwarves/ Features Dwarf Fortress is a single-player fantasy game. You can control a dwarven outpost or an adventurer in a randomly generated, persistent world. Although Dwarf Fortress is still in a work in progress, many features have already been implemented. The world is randomly generated with distinct civilizations spanning centuries of detailed history, hundreds of towns, 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. Trade for all manner of exotic goods with your neighbors. Establish a barony and support the nobility as they make demands of your populace. Beware scheming villains and traitors within. 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! Lay out taverns, libraries, guildhalls and temples to enrich dwarven life and meet their needs. Build a shrine to a volcano deity in a volcano. Serve mushroom wine in the finest goblets. What discoveries will your dwarves make? Accept non-dwarven residents from all over the world as your reputation grows. Surgery, sutures, splints, crutches and more: care for your wounded dwarves instead of leaving them to fend for themselves. Retire your fortress, then unretire it after spending time playing other roles in the world. Honey, wax, pottery, windmills, waterwheels, soap, plaster, wool, eggs, dyes, cheese, glass, animal training, papermaking, parchment, bookbinding and much much more...

Explore without cumbersome plot restrictions -- thriving capitals, villages, catacombs, labyrinths, bandit camps, caves and more! Seamlessly wander the world or travel more rapidly on the region map and in underground tunnels. Travel by day and search for a place to shelter as night falls.
