Fellmark

Dig anywhere
Every metre of Fellmark's world is ground you can dig: about two kilometres down to bedrock, with a lava sea at the bottom. Tunnel, quarry, terrace or hollow out a mountain. The ground fights back. Undercut a sand slope and it pours down on you. Breach the seabed and the ocean follows you into your tunnel. Leave a wide roof unsupported and it caves in. Mine, smelt and forge
Ore runs in veins and pockets, and the deeper you dig the better the metal tends to be. Smelt it at the forge, then make tools, weapons and armour across thirteen metals, from copper to starmetal and voidstone, plus seven alloys. Socket gems into your gear and keep it repaired. Build a home, then a stronghold
Foundation-first building in ten structural sets, from log and stone to titanium and adamantium. Pieces snap together, upgrade in place, need real structural support, and can burn. A living world
Towns and cities, each one different: markets, forges, taverns and castles, with townsfolk who work by day, head to the tavern at night and sleep in their own beds.
Viking villages along the coasts, and longships you can capture.
Twenty kinds of wildlife, bandit camps, raiders and dungeons with bosses.
Horses, sailing boats on a shifting wind, and airships lifted by aether balloons.
Survive the fells
Start with nothing. Find food and water, stay warm in the snow and cool in the desert, and carry light into caves that are truly dark. Hire villagers as miners, woodcutters, hunters, smiths and guards. From forge to factory
In the endgame, power your base with generators, solar collectors and steam turbines, then automate it: ore extractors, conveyors, smelters, assemblers, mass storage, and freight rail between your bases. Better together
