A five-year span for a title, and no further explanation offered. 1980-1984: The Complete Collection puts a date range where most books put a promise, and the shelving supplies the rest of the picture: comedy and humour, fantasy, and science fiction, all three at once.
That combination is a recognisable one. It belongs to speculative comedy, the sort of writing that takes a fixed period and does something impossible to it, and that is where Jason Ayres sits in our catalogue. The word Collection is doing real work as well: this is several instalments gathered into one listing rather than a standalone novel wearing a grand subtitle.
What can be said with confidence stops there, which is no great loss. Thirty-six hours of material will say the rest.
