According to an article Aktueller magazine (05/1986), Nu Wave’s ID game was not only to be produced on the Spectrum, but would later get converted to the Amstrad and Commodore 64 platforms.
It didn’t quite happen though – possibly due to poor sales of the Spectrum title.
The question though is whether anything was actually started on the C64 version, or if it was merely a plan that never came to any kind of fruition.
With a distinct lack of info in the press about a C64 version, we assume it was canned before it was even started. Can you help confirm?
