* PortOverdosed: Both ''Zork'' and ''Enchanter'' have appeared on practically every computer platform ever made.
** The fact that many ''Zork'' games can be played in [=OpenFrotz=], an Infocom game interpreter, means that those it had not been ported to directly can still play it on any system that can compile [=OpenFrotz=]. The engine can be ran straight from a terminal, too.
** ''Zork'' is so port overdosed you can actually play the game ''inside'' another game. There's a trick you can use to wander around the main menu of VideoGames/CallOfDutyBlackOps, where you'll find a computer console that, in addition to copious in-universe emails and government files, contains the entirety of ''Zork''.
* RealitySubtext: Zork: the Undiscovered Underground is filled with this. It's a melancholic, rather gloomy afair where the Underground Empire's ruins are falling apart, several artifacts from the original trilogy are covered in dust or broken, even your trusty lamp needs a few smacks before it sparks back to life, the Grues are going hungry, and you can even find statues of the implementors aka (original creators) talking about the decline of text games and modern graphical adventure games and wondering if there's a place for them anymore. Indeed, it was the last traditional text adventure in the series and was commissioned by Activision as a prequel to Zork: Grand Inquisitor.
