All of my campaign settings have sizable (40 pages+) previews and 4-5 free PDFs each (available through the hyperlinks on the bottom of each entry below). 😀
Eastern fantasy noir steampunk! Think Afro Samurai + Warhammer 40,000 + Ravenloft, or Onimusha + Eberron + Sin City. The lands of Soburin’s 26 prefectures are lushly detailed with over 100 NPCs and monsters, there are huge chapters for three important cities on the continent, archetypes for every class, 14 new races, over a dozen adventures—there’s a lot in here.

This holy decopunk campaign setting is all about adventurers that are evil—for JUSTICE! The world’s technology is powered by inaequa, energy that elongates the lives of creatures with good in their hearts.

This is the most homebrewed and has 6 distinct settings on one world (sword & sorcery & steampunk, high fantasy wuxia, monstrous dieselpunk, subterranean psionic wild west horrors, maritime cthulhu robots and aliens, and ancient aquatic progenitors), a sizable chunk of player options (basically the Adventurer’s Handbook), and the last third of the book is like an NPC Codex for alchemists, cavaliers, gunslingers, inquisitors, magi, ninja, oracle, samurai, summoner, and witches.

Got tired of Shadowrun’s broken rules and made my own cyberpunk variant for Pathfinder 1E that uses the Hyper Score system (sort of like Mythic rules) to make players into super heroes (well, probably not heroes, but you get the idea)

Fundamentally moved the axes of gameplay so that it’s much more like original D&D and focused on survival (in a post-apocalyptic sci-fi setting). Has a randomized world generator built into it so each table’s Wasteland is unique, as well as custom-built weapons, vehicle rules, four new classes and races, warlords like Merlin the Technomage and Drago Chainbeard, and everything you could need to make your own wasteland.
