PDFs of good ttrpg pamphlets that don't include the individual panels as pages are my own personal hell. I WILL NOT PRINT YOUR LOVELY PAMPHLET

140 pages spread across three almost-complete adventures. When will they be ready? Who knows?

I really enjoy reading TTRPG horror modules, and I'd love some recommendations! Well known, or lesser-known, as long as they're good, or even just interesting! (Even if you see this a long time I'm the future, I guarantee I'll still be interested!) ##TTRPG #RPG #Horror #Adventure

I read the DCC module "The Chained Coffin" recently. I see why it gets so much praise. Not the kind of thing I'd run, but purely reading it as a book, it has a wonderful atmosphere.

A simple ruleset I made for car chases that uses a 2D10 Vs D20 mechanic. Made for the One-Page RPG jam 2026. gwions-mistake.itch.io/chasedown

The best thing about writing fantasy RPG things is that people are generally okay with some light anachronism if there are also goblins.

The cover art I painted for my Appendix N Jam 2026 entry, with and without the text and the distressed effect. Pretty happy with how it turned out! gwions-mistake.itch.io/zeffans-laug... #osr #art #AppxNJam

I loathe AI art, but the proliferation of it has lowered my standards for an acceptable level of human-made art so much that I now find my own artistic level much more acceptable, so I'm more productive. Funny old world. #art

One last post, and I'm caught up with posting things I've made here. I made this for the Vaults of Vaarn Summer Jam on itch (which is still ongoing!) It's a small adventure for Vaults of Vaarn about smuggling. gwions-mistake.itch.io/a-tavaarn #OSR #Vaarn #VaultsOfVaarn #TTRPG

My Appendix N Jam 2026 entry! I submitted pretty early, and it's been really cool seeing the other, better, entries coming in all month. Very fun! gwions-mistake.itch.io/zeffans-laug... #AppxNJam #OSR #TTRPG

Since I'm still new, one of just a few quick posts of what I've made so far. www.drivethrurpg.com/en/product/5... I released "The Mechanism", my first adventure, in June, my most major completed project and what I am proudest of. I learned a lot from it. #OSR #OSE #TTRPG

Hello! New here! For the past couple of months I've been writing and drawing some TTRPG adventure things, and this seems like the best place to discuss things at the moment, so here I am! I'll probably post links to some of the things I've made, and then some art and stuff maybe, who knows.
