I'm Tarn Adams of Bay 12 Games, co-creator of Dwarf Fortress. AMA!
Hello reddit and /r/dwarffortress! I'm Tarn Adams, one of the designers (with my brother Zach) of Dwarf Fortress, a dwarven colony-builder/RPG/fantasy world simulator. The game has been free to download and play since 2006, and development is ongoing.
I will be here starting at 4:00 Pacific. Zach is here too. Also Scamps.
Edit: 11PM. I guess 7 hours is enough, he he he. My eyes hurt. I'm sorry I couldn't get to everything. I tried to do the up-voted ones, but I'm sure I missed something amid all the shifting. Thanks for asking questions! That was a lot of fun.
