Advanced Crimson Dragon Slayer

Advanced Crimson Dragon Slayer


"D&D in arcade mode!" ~ Prince of Nothing This is my own heavily house-ruled hack of B/X and 5e, suitable for one-shots, convention games, virtual play, and even face-to-face campaigns.  I'm currently 16-sessions into my Crystals of Chaos campaign set in the eldritch, gonzo, science-fantasy, post-apocalyptic world of Cha'alt.  Check out my session reports on Venger's old school...   [click here for more]

Crimson Dragon Slayer

Crimson Dragon Slayer


Take science-fantasy gonzo, then add 80's sleaze and cheese! This is my own contribution to the OSR / fantasy heartbreaker genere of paper & pencil roleplaying games.  Crimson Dragon Slayer is heavily inspired by the 1980's.  The parts of it that are god-awful are god-awful on purpose (mostly).  Your adventuring party might contain a robot ranger with laser...   [click here for more]

Crimson Dragon Slayer 1.11

Crimson Dragon Slayer 1.11


This little PDF is a re-boot of the Crimson Dragon Slayer RPG.  It takes two steps back and one in a slightly new direction.  Less comedic, gonzo, 80's references and more dark, weird science-fantasy.

How to Game Master like a Fucking Boss

How to Game Master like a Fucking Boss


This is the accumulated wealth of my 30 years playing, designing, and (most importantly) Game Mastering paper & pencil roleplaying games.  I wrote a book that I would want to read, something I could refer back to again and again.  Not every suggestion or recommendation is worth its weight in gold, nor will they be to everyone's taste.  However, I believe there's enough personal wisdom shared...   [click here for more]
