Kitfox Games plans Dwarf Fortress anniversary stream with Tarn and Zach Adams
Kitfox will mark Dwarf Fortress' 20th anniversary on August 5 with Tarn and Zach Adams replaying the 2006 build and handing out awards to their inspirations.

Kitfox Games will mark Dwarf Fortress’ 20th anniversary with a special stream on August 5 on its Twitch channel, where Tarn Adams and Zach Adams will play the original 2006 build. The broadcast will also include awards for gamedevs and creators who inspired the Adams brothers over the decades, turning the stream into both a live look back and a nod to the people who shaped the game’s long run.
The anniversary lands 20 years after the original public release on August 8, 2006, when Bay 12 Games put out Dwarf Fortress version 0.21.93.19a. Development had already been underway since October 2002, and Bay 12 says the project’s home base has been online since December 2000, which puts the first alpha in the middle of a much longer stretch of tinkering, iteration, and community support.

That early build is the right lens for this milestone. The August 5 stream will let players see how far the game has traveled from the first public version to the Steam era, where Dwarf Fortress launched on December 6, 2022 with a new versioning scheme and an official graphical set. Those changes matter because they mark the rare point where a cult favorite with deep roots in ASCII and donations had to translate itself for a larger audience without losing the systems-first identity that made it Dwarf Fortress in the first place.

The commercial arc around the game has only widened the celebration. Tarn Adams said Dwarf Fortress passed 1,000,000 sales on Steam, while reporting from early 2023 put the Steam release at 160,000 units in its first 24 hours and 500,000 by the end of 2022. Serenity Forge has also been selling a Dwarf Fortress 20th Anniversary Archival Collector’s Edition for $149.99, a pricey companion piece that underscores how far the old two-person project has come.
When Tarn and Zach sit down with the original 2006 build, the appeal will not be nostalgia for its own sake. It will be the chance to watch the first recognizable version of Dwarf Fortress sit in the same frame as the Steam release, the million-seller status, and the anniversary merchandise, all while the game’s most stubborn ideas still carry through the years.
