In case you haven't seen it, Jody Macgregor has a review of HeroQuest: The Fellowship of Four on PC Gamer that's interesting for two reasons. First because the book came out 33 years ago (not that I'm complaining; a good review is worth waiting for) and second because Jody might be the first person in 33 years to spot the four literary antecedents that I drew on (oh, "swiped from" if you must) to spice up the narrative styles of the mage, elf, barbarian and dwarf.
That said, he did overlook the nod to Salman Rushdie's book The Satanic Verses in the opening chapter, which begins with the narrator falling from an altitude of several thousand metres. I didn't attempt to emulate Sir Salman's prose style, which I'll confess is a mite too rich for my tastes.
There's little chance of the book ever being republished, nor the sequels, as the fellow from Hasbro really didn't like it much. Backers of the Jewelspider Patreon might have seen glimpses, but that's only a rumour and I can't possibly comment. And I see you can buy scans from HeroScribe.org. Failing that, listen to the insightful Mr H J Doom talk about it on Fantastic Fights.
