System Crafting: Creating and Revising TTRPGs at Gen Con 2026

Writing a RPG can seem daunting, but creators now have more options and tools available to help them. Do you want to write a game from scratch or use an existing open system? What steps should you take first? How long does it take? Peter Petrusha of Imagining Games (Chew, Dreamchaser), Ross Payton (Base Raiders, Role Playing Public Radio podcast), Caleb Stokes (Red Markets, Delta Green: God’s Teeth), and Julian Kay (Mutants in the Now) have answers. This panel was recorded at Gen Con 2026. The screenshot is from The Cthulhu RPG timeline.
