"Rogue" became popular in the 1980s among college students and other computer-savvy users in part due to its inclusion in 4.2BSD. It inspired programmers to develop a number of similar titles such as "Hack" (1982) and "Moria" (1983), though as Toy, Wichman, and Arnold had not released the source code at this time, these new games introduced different variations atop "Rogue". A long lineage of games grew out from these titles. While "Rogue" was not the first dungeon-crawling game with procedural generation features, it introduced the subgenre of roguelike RPG procedurally generated dungeon crawlers with Dungeons-and-Dragons-like items (armor, weapons, potions, and magic scrolls) that also had permadeath (permanent death) and an overhead graphical albeit via ASCII drawings, as opposed to text descriptions in natural language such as can be seen in Adventure/Colossal Cave and the original Zork games.
