Dwarf Fortress

The world sim to rule them all, Dwarf Fortress typically delivers about four or five hours on the Steam Deck, if not more. There’s a lot of complexity, maybe too much, going on in this game, but that doesn’t stop the Steam Deck from going long after you’ve watched multiple civilizations of yours bite the dust…or maybe that’s just a me problem.
While Dwarf Fortress is fully playable on the Steam Deck and launches with a very accommodating set of controls, the text can be quite small. Steam button + L1 is going to be your best friend here.
