John Alan Martinson
Welcome to John Alan Martinson's Games!
I'm John Alan Martinson, an independent tabletop role-playing game designer, author, professional voice actor, and longtime Game Master. I've spent more than three decades playing and running tabletop RPGs, narrated over 120 audiobooks, and devoted years to developing original games and fictional worlds.
My philosophy of game design emphasizes player freedom, cinematic action, meaningful consequences, realism, and unforgettable storytelling. I believe the greatest adventures emerge when players have genuine choices, their characters' actions matter, and Game Masters have the tools to bring extraordinary worlds to life.
My flagship creation is 👑Kingsmark, an original heroic fantasy tabletop role-playing game set in the medieval fantasy world of Sylva. Powered by my original ⭐ Jack's Cinematic d12 (JCd12) system, Kingsmark features exciting tactical combat, 17 Character Classes, an innovative 🩸Physical Wound and 🧠Mental Trauma system, dangerous magic, and a world where adventurers can rise from humble beginnings to become legendary heroes.
The 556-page Kingsmark: Player's Handbook — First Edition is available here for just $10. It includes everything necessary to begin playing, including four ready-made characters and a complete introductory dungeon adventure. Five additional companion books are planned to expand the game.
I intend to continue publishing tabletop RPGs, fantasy fiction, adventures, and resources for players and Game Masters. Whether you're an experienced role-player or completely new to tabletop gaming, I invite you to explore my work.
