Tarn Adams is the co-founder of Bay 12 Games and is best known for co-creating Dwarf Fortress, which was released in 2006 and is celebrating its 20th anniversary. He has recently been playing The Planet Crafter, a terraforming game, and has logged 1,454.5 hours in Factorio, a factory-building simulation. Adams does not have a single game he would never uninstall but frequently plays Caves of Qud. He uses Ableton, a music sequencer, as essential non-gaming software. His desktop is about half full with various folders and .txt files, including a nostalgic folder for BASIC games from the '80s.
