"Quake" was the only game to rival "Doom" as the most popular game to speedrun. People first started recording demos of "Quake" playthroughs when it was released in June 1996 and sharing them with others on the demos/e directory in Cdrom.com's "Quake" file hierarchy. There were two distinct kinds of demos: those in which the player killed all monsters and found all secrets on the map (called 100% demos) and those in which the player ignored these goals in order to finish the level as fast as possible (called runs). All levels were, at that time, recorded solely on the "Nightmare" difficulty level, the highest in the game.
