  • Fever-Dreaming Marlinko (OSR) The second big Hill Cantons-book clocks in at 72 pages, 1 page front cover, 1 page editorial, 1 page ToC, 2 pages of SRD, 1 page back cover, leaving us with 66 pages of content, laid out in the classic digest (A5-ish) standard, so let’s take a look!   This review was requested by my patreons, to be undertaken at my convenience. I do own the print version of this booklet and my review is primarily based on the print version. I did also consult the pdf.   Content-wise, I probably should state that if you’re a super-devout Christian, one particular aspect of the supplement *may* potentially offend you; it also contains profanity. I found it hilarious, […]

  • By this Poleaxe (OSR) This little FREE pdf clocks in at 5 pages, 1 page front cover, 1 page editorial, leaving us with 3 pages of content.   This supplemental pdf basically provides a small-scale battle-rules variant of the mass combat system presented in “By this Axe.”   Each squad is made up of up to 5 combatants and is represented by a single figure.   Squads have 5 attributes: AV (attack value), DV (defense value), MV (morale value), HTK (hits to kill),  M (movement).   Attack value is a squad’s ability to hit on a d10; total HD and divide by 5. A table of modifiers and AV by HD is provided. DV is calculated by averaging the AC […]

  • By this Axe (OSR) This pdf clocks in at 12 pages, 1 page front cover, 1 page editorial, leaving us with 10 pages of content, so let’s take a look!   So, what is this? Well, it is basically a mass-combat mini-game system for Labyrinth Lord, and not, as the title may suggest, a Kull-reference.   The system wastes no time and immediately begins with its rules: There need to be 2 or more armies. Each army will have 2 or more units.   A unit of infantry consists of at least 3 figures, and may contain up to 25. Cavalry units contain at least 2 figures, up to 15. Players have free control over formation and how a unit […]

  • Slumbering Ursine Dunes (OSR) This adventure/location-supplement clocks in at 68 pages, 1 page front cover, 1 page back cover, 1 page editorial, 2 pages of SRD, leaving us with 63 pages of content. It should be noted that the Cave Dwarf race/class and War Bear race/class take up 3.5 of these pages (including a nice war bear marching song) – both are also featured in the PWYW Hill Cantons Compendiums and I have covered them in my reviews of these files.   This review was moved up in my reviewing queue as requested by my patreons.   This module/location is written for the Labyrinth Lord rules and takes place in the world of Zĕm, which is inspired by Slavic folk […]

  • Strange Stars Game Setting Book (system neutral) This setting book clocks in at 32 pages, 1 page front cover, 1 page back cover, 1 page advertisement, leaving us with 29 pages of content, so let’s take a look, shall we?   This review was moved up in my review-queue as a non-prioritized review at the request of my patreons.   Old Earth isn’t even a legend anymore, even its location lost to the ravages and vastness of space and time. An undetermined time after humanity spread to the stars, the Archaics rose in their floating, crystalline cities, constructing a hyperspace travel network and engaged in planetary-scaled engineering; theirs was an age where a noble may rule a whole world – […]

As you can glean, provided you’re familiar with SWN, the task of converting the rules material to another OSR-system is relatively […]

  • Weird Adventures (OSR) This massive sourcebook clocks in at 165 pages, 1 page front cover, 1 page ToC, 1 page editorial, 2 pages of SRD, leaving us with 161 pages of content, so let’s take a look!   So, what is this? Well, picture a setting, the Strange New World, that puts fantasy tropes in an era reminiscent of the interim between the two World Wars, as seen through the lens of the classic pulp magazines of old. The history of the world is thus somewhat akin to what you’d expect, though it should be noted than nice, poster-style artworks provide cliff-notes versions of what once was. It should be noted, though, that the focus of this book lies exclusively […]

It should be noted that, while this pdf explains the concept of corelands, borderlands and weird, I still maintain that it’s smart to read up on the former pdf before reading the two flavor pages that kick off this book: In these, both the city of Kezmarok and Marlinko, both with brief notes on surrounding areas and the […]

  • The Hill Cantons Cosmology (OSR) This brief cosmology clocks in at 8 pages, 1 page front cover, 1 page editorial, leaving us with 6 pages of content, so let’s take a look!   So, this pdf is exactly what is says on the tin – a description of the cosmology of the Hill Cantons, which serve as a backdrop for several of the modules put out by the Hydra Collective. But it is frankly more than that.   The world described here would be called Zěm, and after the header, which explains how the world came to be, we begin with a dialog-like frame-narrative that is hilariously irreverent. In the beginning, there was void (or has world-matter existed before?) and […]
