It was part of a design competition. So the rules are very light. It is almost improvisational. It is intended to be a simple crafting process that emulates Dwarf Fortress in spirit. The tables provided are based on things that happen in the game. It is expected that anyone attempting to play the game must be familiar with the fortress mode of Dwarf Fortress, and would then play out a crafting process of making a fort along with spontaneously introducing random elements into the flow of play as it does in the video game.
