Other than the art itself, the Calendar of Nechrubel is probably the "killer app" for Mork Borg. It is a countdown clock on your entire campaign, and the random nature leads to layering miseries that add complications to your continuing misadventures.

Despite Mork Borg's pitch-dark aesthetic, it's basically a (dark) comedy game, too miserable and grotesque to take seriously. Everything is a bit tongue-in-cheek, and the result is a solid game with a great and expansive fan community. Mechanically, it's not that special, but the aesthetic is really fun.
