Why is Pixel Dungeon so underground? To me, it seems basically like a turn-based souls game. I am playing this game for 2 years now (The OG Pixel Dungeon) and i still find new content, like its infinite.
Pixel Dungeon is a rogue-like, those existed way before Dark Souls. There are even text-based games running in a Unix terminal, I think Nethack is one of the oldest, if not the oldest itself.
Hack is a 1984 roguelike video game that introduced shops as gameplay elements and expanded available monsters, items, and spells. It later became the basis for NetHack.
Rogue (also known as Rogue: Exploring the Dungeons of Doom) is a dungeon crawling video game by Michael Toy and Glenn Wichman with later contributions by Ken Arnold. Rogue was originally developed around 1980 for Unix-based minicomputer systems as a freely distributed executable.
