A profile of Tarn and Zach Adams, creators of the computer game Dwarf Fortress:

Dwarf Fortress may not look real, but once you’re hooked, it feels vast, enveloping, alive. To control your world, you toggle between multiple menus of text commands; seemingly simple acts like planting crops and forging weapons require involved choices about soil and season and smelting and ores. A micromanager’s dream, the game gleefully blurs the distinction between painstaking labor and creative thrill.
