This was to be a text adventure release in a nice large clam box by Classic Quests around 1986 time. This was something that was done to a few Supersoft games written by Brian Cotton, so we believe that Brian was also the author of this game. It seems some of his adventures were enhanced slightly for release under the Classic Quests label (part of Supersoft), which was the case for Forestland that had a release in 1983 by Supersoft.
It was due for release overall on the Commodore PET, 64, 128 and Plus 4, Amstrad CPC, 6127, PCW, PC and IBM PC compatibles. A CPC version seems to have surfaced, which may have been the Classic Games version. It seems no other versions have surfaced, but contributor Strident has done some investigations which show evidence that the Classic Quests versions of Catacombs and Forestland were released on multiple platforms: http://8bitag.com/info/catacombs.html
So is this just an obscure release waiting to be found? At the very least you can check out the 1983 game for now.
More soon we hope…
