NetHack: The Next Generation was Sebastian Klein's variant of NetHack 3.1.3. Its main features are Geek as a new role, and various monsters and jokes borrowed from the works of Douglas Adams. The documentation also describes a feature that allows players to reroll new characters. They may even specify minimum features! This is normally something that we expect of Angband, not NetHack. However, TNG seems to be more popular among Japanese players. Apparently TNG was ported to JNetHack, resulting in "JNetHack-3.4.3-0.8-TNG".
