1001 Video GamesReturn to Zork appears in the book 1001 Video Games You Must Play Before You Die by General Editor Tony Mott.
BugsThe endgame has one of the most frustrating bugs ever in the history of adventure gaming. In order to reach the final confrontation with the main villain, you have to throw every single item in the game that isn't nailed down into a pit to raise a bridge. The problem is, due to various bugs, you'll sometimes end up not raising the bridge even after throwing everything into the pit, making it impossible to progress to the ending and resulting in you having to restart the game from the very beginning.
Because this game was made before the WorldWide Web allowed for the widespread distribution of patches to correct post-production bugs, this error was never addressed and anyone playing the game will just have to hope they're lucky and don't run into it.
Cut ContentThe singing tree mentions some "friends" who have brought you to her. This is a reference to the Mushroom People, who were in the game's original screenplay and design but ultimately cut out of the final version. The tree's reference to them was accidentally left in.
DevelopmentThe creators of Return to Zork weren't familiar with the rest of the series, never having actually played any of the original text games.
Encyclopedia FroboziccaNino Ruffini, compiler of the Encyclopedia Frobozzica, merged the encyclopedia entries from Sorcerer and Zork Zero with text from some of the other Infocom games' box contents and a few of his own entries. The original version of the Encyclopedia was circulated around Delphi and the rest of the Internet until Activision came across it and asked Ruffini for permission to use it in RTZ so they wouldn't have to recompile everything themselves.
Floppy VersionThe floppy version of this game came on an incredible 21 floppies! In order to play the game, you had to spend a fair amount of time installing it first by floppy swapping. It proved to be one more reason to get a CD-Rom drive for your computer.
Macintosh VersionIn the Macintosh version of Return To Zork, many things that were not required for completing the game were eliminated. For example, in the original DOS version, showing the matches to the Lighthouse Keeper would trigger a response "Thank you, I never smoke *cough*". In the Macintosh version however, he simply has nothing to say about it.
MPEG VersionA special version of the game was released with re-encoded MPEG video for both DOS and the Macintosh in 1995. It was exclusively sold as OEM version. The Macintosh version came with the Apple MPEG Media System card and the DOS version came with the ReelMagic card.
Planetfall TrailerReturn to Zork came with a trailer for Planetfall. Infocom/Activision was developing a graphic update of the the verenable favorite. Unfortunately, the game never saw the light of day.
ReferencesThe game's intro video begins with the text on a black screen "You are standing behind the white house. In one corner is a small window which is slightly ajar.". This text is copied from the first thing shown on the screen of the first Zork game. The video then shows you the house and rotates around it before finding the sweepstakes invitation in the mailbox (which is not what happens in the first Zork game).
