Unseen:
I've become familiar with some of the so-called "retro clones" while playing on Rpol. That one, in particular, is pretty good.
I'm only just familiarizing myself with it for the first time-- I'm not (yet) a huge fan of
Swords & Wizardry itself, but there are
tons of offshoot games based on it that I'm really excited about and... I want the extra context.
Unseen:
I also kind of like "Old School Essentials," that includes all the classes and races from the old Unearthed arcana book, and makes them old style D&D suitable.
I am, however, a huge fan of OSE and Necrotic Gnome and I'm really looking forward to the different fantasy genre sourcebooks that Gavin's been promising--
eventually.
Unseen:
Is Shroompunk your own system, then?
Yeah... it's a number of different things right now.
It's a sub-genre of sword & sorcery fantasy fiction and a sub-genre of fantasy roleplaying that I'm trying to codify and popularize: ultra-low fantasy with ultra-high magic, driven by fairytale logic, and inspired more by classic videogames than mythology and folklore.
It's the setting I am worldbuilding for that fiction/gaming genre-- an infinite, sprawling network of Worlds connected by the living, dungeonlike Warp Zones; populated by planetouched humans, honorable tortles, mischievous robotic tinkers, and more. My WIP novel is titled
The Oathbreaker King: a Shroompunk Tale and it's about two brothers on a quest for a crown and throne that neither of them wants.
And yeah... my primary objective is to publish
Shroompunk as my own "unique" RPG system-- it's a mashup of modern D&D mechanics and OSR gameplay principles, that I'm hoping to be able to reuse with my
Knights of the Astral Tide space fantasy setting, which is what sparked my recent interest in
Phantasy Star and
Starfinder.
