1001 Video GamesThe Arcade version of Gorf appears in the book 1001 Video Games You Must Play Before You Die by General Editor Tony Mott.
Planned sequelA prototype sequel to Gorf titled Ms. Gorf exists only as source code stored on a series of 8-inch floppy disks that unfortunately can't be compiled apparently due to the obscurity of the programming language it was written in (Forth) and being done in a software environment that cannot be reproduced. However, some gameplay footage of the the game exists in a demo reel of a never aired television show Wired In.
References of the gameArcade machine play screens of Gorf can be seen in these movies - 1982's Fast Times at Ridgemont High, and 1983's Joysticks. An arcade cabinet can also be seen in 2006's The Benchwarmers.
TitleThe programmer called it Gorf since it's Frog spelled backwards. It is also an acronym for 'Galactic Orbital Robot Force'.
