One of C64s most heart breaking stories - a fully completed and faithful Commodore 64 port of Parasol stars was lost forever when the developer - Colin Porch's wife destroyed all his disks in an argument. The story was the subject of an infamous cover up, reported by Ocean and Zzap magazine as a burglery, but has recently been covered in great detail by Games that Weren't and Commodore Format which I recommend you read more about if you haven't already.
Could the story have a final twist in the tale? As yesterday Doc Cosmos developer Simon Jameson has revealed he has been working on his own port of Parasol Stars, and has even shown off some early demo footage for us all.
