Polygon sat down with one of the creators of Dwarf Fortress
The truly exciting thing about Dwarf Fortress is that it proves that deep, detailed simulation is well within our reach.It suggests whole new genres of games that have yet to be created; imagine a typical fantasy RPG (or perhaps one that plays more like Mount&Blade) where the entire world is simulated as you play, so every choice you make has logical consequences. The possibilities are endless, and while Dwarf Fortress is a great game on its own, it's really just scratching the surface of what can be done with world simulation.
