Black Coffee Games fundamentally understands that an RPG system optimized for profit cannot also be optimized for game quality and player experience. So we created Spectrum to give creative power and agency back to the players.

What is Spectrum

Spectrum is a TTRPG system built for collaborative storytelling where every player is a co‑author. The mechanics are designed to add diverse, unique, and infinitely varied paths for character growth and development. More importantly, Spectrum gives the Narrator and players the freedom, flexibility, and stability you need to flex your epic badassery.

If you enjoy creating lore‑rich backstories, experiencing meaningful character growth, immersive story progression, and sinking into the role of your character – welcome to the last system you’ll ever need to learn.

Not into that? If you’re searching for yet another RPG that rewards power‑gaming, meta‑gaming, class hyper‑optimization, and rules‑lawyering – that’s fantastic. But Spectrum may not be for you. Fret not: we’re developing a murder hobo system later. Stay tuned.

What’s Different About Spectrum

Genre‑agnostic

Because who are we to tell you what story you want to tell?

No classes, no archetypes, no optimized builds

Just characters with feelings and bad decisions.

Nonlinear mechanics

Because your character arc and story shouldn’t be predictable or formulaic.

Built for character‑driven growth and lore-rich backstories

Because we like emotional damage more than fireball damage.

Free, flexible rules

Because creativity shouldn’t have a paywall or fit neatly into a box

Spectrum’s Math

Linear math used in traditional game systems is simple, predictable, and safe. But what adventure have you ever experienced that was any of those things? What story do you want to hear where the possible outcomes of choices were predictable or formulaic?

Linear math lends to rigid and unyielding dynamics that easily lose their organic qualities and become disassociated from storytelling. As the innumerable variables of every moment coalesce and compound, the resulting effect can very rarely be expressed with a simple one-to-one formula.

Spectrum uses nonlinear math because real life isn’t a straight line – and neither are good stories. We hope our use of nonlinear math will better represent the interplay of constantly shifting variables in everything, everywhere, all the time.

We hope that this break from the standard creates more dynamic and exciting possibilities for your stories to blossom. Is it the right way? You tell us.

Why Storytelling Matters

Stories aren’t just entertainment. Stories are how humans have made sense of the world, even before we were drawing on cave walls. Every step of our evolution has been shaped by the stories created and shared. They’re how we learn about the world, develop empathy, process trauma, and connect with each other across every boundary. Which means storytelling isn’t a hobby, it’s arguably the most important human thing you can do.

You are made of stories and they all add up – to identity, to connection, to the great, messy, glorious pile of shared experience that makes life worth living. We built Spectrum because we believe that. And because we think you deserve a system that gets out of the way and lets you tell your story how you want to tell it.
