Carl Williams writes, “Eye of the Beholder is a title that never saw release on the Commodore 64, for whatever reason upon release in 1991 SSI only saw DOS and Commodore Amiga as worthy platforms. Later on we would see Eye of the Beholder ports for the Super Nintendo, Sega CD, and overseas the PC-98 (and then there was the unreleased Atari Lynx version). Par for the course though, independent homebrew developers have taken it upon themselves to port Eye of the Beholder to new platforms the Commodore 64 for instance.”
