NetHack

NetHack is an open source single-player roguelike video game, first released in 1987 and maintained by the NetHack DevTeam. The game is a fork of the 1984 game Hack, itself inspired by the 1980 game Rogue. The player takes the role of one of several pre-defined character classes to descend through multiple dungeon floors, fighting monsters and collecting treasure, to recover the "Amulet of Yendor" at the lowest floor and then escape... It is identified as one of the "major roguelikes" by John Harris.[8] Comparing it with Rogue, Engadget's Justin Olivetti wrote that it took its exploration aspect and "made it far richer with an encyclopedia of objects, a larger vocabulary, a wealth of pop culture mentions, and a puzzler's attitude."[9] In 2000, Salon described it as "one of the finest gaming experiences the computing world has to offer" https://en.wikipedia.org/wiki/NetHack

Sawyer tweets: Nethack is a skinner box which intermittently reinforces the habit of translating emotionally evocative stories into explicit discrete predictions quantified by numerically precise probabilities. It's a Rationalist Factorio.
