This Cyclopean textwall is a review of the Trail of Cthulhu RPG which got way, way out of hand. I considered breaking this into several parts, but then you’d get the thing where people start commenting and responding to an earlier part when they’ve not yet read and digested the later parts, so you’re getting the whole epic in one big post.
Disdain For Derlethians
My favoured flavour of Lovecraftian RPG is and always has been Call of Cthulhu, which may partly be down to my familiarity with the system and the sheer amount of material out there for it but I think also comes down to the strength of the original design (the lack of major revisions from early editions to 6th Edition is testament to this) and the way that 7th Edition has made genuinely useful improvements to the system (along with optional systems like luck spends or pushing rolls which help dial back the swinginess of the system).
Some of the significant improvements to 7th Edition seem to be a reaction to or refinement of ideas from Trail of Cthulhu from Pelgrane Press. Trail has carved out a niche for itself as perhaps the most significant of the surprising number of “it’s Call of Cthulhu, but with a different system” games out there, and I think you can track this pre-eminence to three important factors. The first is that Pelgrane have gave Trail it a fairly substantial support line right out of the gate, whilst much of Trail‘s early run has coincided with the old regime at Chaosium being in a bit of a decline and therefore not producing so many Cthulhu products in their own right (though in fact Trail is made by arrangement with Chaosium, so they probably get their cut out of this). The second factor which made Trail stand out from the crowd comes from it being written by Ken Hite, who’s well-versed both in Lovecraftiana and in horror in general – his Nightmares of Mine is still the definitive text on horror RPGs as far as I and many others are concerned. The third factor which put Trail on the map comes from it being a Lovecraftian implementation of the GUMSHOE system by Robin Laws, which unlike most systems people try to convert Call of Cthulhu to is designed from the ground up to support investigative RPG play.
That said, I resisted trying out Trail for a long time. There is an irrational part of me which largely rejected it because it’s named after August Derleth’s absolute worst Cthulhu Mythos story, an incredibly repetitive “novel” lashed together from a set of short stories which are outright mutually contradictory – and not contradictory in a cool, evocative cosmic horror sort of way so much as a “this is a massive display of basic authorial incompetence” sort of way. Hite seems to have this enjoyment of Derleth which is weirdly uncharacteristic of someone who is even remotely discerning in terms of their reading material – tastes do vary, but there is such a thing as objectively bad writing and Derleth’s Trail is living proof of that – though Hite at least admits that his is not the majority opinion.
