As an experienced tester of this game, from the mechanics you've seen so far, and those you expect to come out, how likely is my dream of an underground dwarven city?
you cant build structures underground, like you cant have an underground log house, and honestly, i dont know why. But, knowing that you can still make your houses and all the other shit out of the stone. I do think it is definitely possible but it will be one hell of an endeavor, as for every bit you dig, you have to put it somewhere, and that means your going to end up creating another mountain somewhere else lol, there is going to be the biggest freaking pile of dirt and stone somewhere outside of your place. You will also have to drink water to recover your stamina, because digging is tiresome, so you will be constantly chugging water, and without someone continually bringing in water to the caverns, you are going to have a helluva grindy walk every time your stamina runs out. Also, and i dont think many people know of this, but they wanted to add a sort of native, or just baddie AI that can attack you, and i do believe they spoke once of a sort of Pygmy style man that would live underground, or in caves. Though that hasnt been implemented, and idk if it will. You might have to contend with that, but if you have enough "dwarves" im sure anything is possible.
