For this game, I’ll be using the concept outlined in this post .
🚀 The Journey Begins
Aside from wargaming, RPGs have been a long-time passion of mine. It’s been quite a while since I last ran a proper campaign, and for the past few years, I’ve been drawn to the idea of solo RPGs. My first foray into that space was with Ironsworn by Shawn Tomkin—I loved its gritty tone and mechanics so much that I immediately backed Starforged on Kickstarter when it launched.
Being a serial system-switcher, I’ve spent years hopping between RPG systems, chasing different ideas and concepts. One campaign idea that’s been rattling around in my head involves characters who were once powerful beings in the world, now stripped of their memories. The adventure? To rediscover who they were—and carve out a new identity in a changed world. The concept draws loose inspiration from the power and style of shows like Blood Blockade Battlefront and Solo Leveling. In essence, I wanted to run a singular hero high powered game this time around.
💡 Game Idea
To that end I have put together a simple system for solo play. It’s based on a myriad of rules I’ve read and played over the years, combining ideas from both RPGs and wargames: streamlined mechanics, flexible character creation, and tools for emergent storytelling. One Hero Engine is a solo-focused, narrative-driven RPG built around a fast, flexible D20 resolution system. Instead of rigid skills or feats, it uses tags to define your hero’s unique traits, with progression tied to story milestones rather than XP. Combat is quick and heroic, using opposed rolls, Fray Dice for ongoing pressure, and dynamic morale checks for enemies. A lightweight oracle system drives narrative choices, while spellcasting and Mythic Spells empower dramatic, cinematic moments.
It’s a system built for players who want more than just numbers on a sheet—it’s for those who want to become their hero. Whether you’re forging a legacy through fire and battle or unraveling secrets in quiet ruins, the mechanics are there to support your choices and let the story unfold naturally. It’s bold, flexible, and tuned for dramatic pacing—just one hero, one story, and endless possibilities. I’m trying out this system and have put the rules up here .
