In the summer of 1981, at Pacific Origins in San Mateo, two men sold roughly a thousand copies of a 56-page staple-bound booklet from a print run of fifteen hundred.

The booklet was called Champions.

Within a few years, the ideas inside it had begun to spread through RPG design: comprehensive point-buy character creation, effects-based power design, and disadvantages traded for character-building currency.

George MacDonald created much of the engine.

Steve Peterson made it run.

That distinction matters.

It does not diminish Peterson. It identifies him precisely. He was not simply an assistant. He was not just a typist. He was the person who helped turn a revolutionary design impulse into a coherent, publishable game.

The Partnership

The attribution story is unusually clean by tabletop standards.

MacDonald was the primary mechanical innovator. He began by modifying Superhero 2044’s system, then moved toward an original powers framework and point-buy character creation structure that would define Champions.

Peterson’s contribution was different in kind.

He organized. He reviewed. He typed. He systematized. He helped turn a creative explosion into something people could buy at a convention, take home, read, and actually play.

That work is architecture.

MacDonald imagined the house. Peterson helped draw the blueprints, pour the foundation, and make sure the walls were load-bearing.

What They Built Together

Champions introduced or crystallized three ideas that became major parts of RPG design.

The fully developed point-buy character creation system was the most consequential. Earlier games had experimented with point allocation, including Superhero 2044 and The Fantasy Trip. Champions applied the idea comprehensively: characteristics, skills, powers, and disadvantages all lived inside a unified cost framework.

Instead of rolling to discover who your hero was, you built the hero you meant to play.

The effects-based power system may have been even more elegant.

Champions did not need a separate bespoke rule for every named superpower. It defined powers by mechanical effect. An Energy Blast could be a laser, an ice bolt, a magical spell, or a mutant plasma burst. The rules cared about what the power did. The player supplied what it looked like.

That distinction changed superhero RPG design.

The disadvantages-for-points mechanic completed the economy. Characters could take flaws, obligations, vulnerabilities, hunted enemies, psychological limits, or complications in exchange for additional build points.

That made characterization mechanical.

Your hero’s weakness was not just backstory.

It was part of the budget.

These ideas were not Peterson’s alone. They were the product of collaboration. MacDonald supplied much of the conceptual spark. Peterson helped build the framework that made the spark functional.

Both contributions were necessary.

Neither alone would have produced Champions as it reached the table.

The Architecture

The Hero System that grew from Champions is one of the most internally consistent RPG frameworks in the hobby.

Its core principle is simple and powerful: almost everything can be built from the same point-cost toolkit.

Superpowers. Magic. Technology. Martial arts. Strange alien abilities. Spy gear. Pulp tricks. The label changes. The underlying construction logic remains.

The 3d6 bell curve creates predictable probability. Endurance gives powers a shared resource cost. Advantages and limitations let players tune abilities to match fictional intent. Disadvantages turn flaws and story pressure into mechanical economy.

The system supported multiple editions across more than four decades. It sustained long campaigns. It scaled from street-level heroes to cosmic entities using the same design grammar.

It was not perfect.

Strength was famously efficient. Disadvantages could be gamed. Character creation could take hours. High-powered fights could produce enormous handfuls of dice.

But the architecture held.

Six editions. Decades of play. A fan base that still understands the system as a toolkit, not just a game.

The bones Peterson helped design were strong enough that others could keep building on them long after the original partnership ended.

Who Built On It

The propagation evidence is unusually specific.

GURPS is the most important descendant. Steve Jackson developed GURPS after Champions and has acknowledged Champions as part of the inspiration for point-built universal design. GURPS adopted point-buy creation, advantages and disadvantages, 3d6 resolution, and the dream of a universal system.

Mutants & Masterminds also sits in the Champions lineage. Steve Kenson wrote material for Champions before creating M&M, and M&M adopted point-buy superhero construction and effects-based power design.

The influence also traveled through other superhero and universal systems, through fan culture, and through the expectation that a superhero RPG should let you build almost anything if you can pay the cost.

Hero Games produced a long tail of books, periodicals, editions, and adaptations. Champions moved into comics through licensed and related publishing. Champions Online brought the name into digital gaming.

Ron Edwards later returned to first-generation Champions through Champions Now, describing the original game as something like a creative studio for players.

That is the point.

Champions did not just give players heroes.

It gave them a workshop.

Five Years

Peterson’s active tabletop design peak was brief.

From 1981 to 1985, the output was intense: Champions, early Hero Games development, Espionage!, Justice Inc., Danger International, and Fantasy Hero. After that, Peterson moved into the video game industry, working in marketing and production roles.

He returned for Champions 4th Edition in 1989 with MacDonald and Rob Bell. He returned again in the Fuzion era, when Hero System material was merged with R. Talsorian’s Interlock ideas.

Fuzion did not become the breakthrough its designers hoped for.

That matters for Mastery.

Peterson’s career in games was real and substantial, but tabletop system design was not a forty-year solo craft arc. It was a concentrated early chapter followed by other roles in games, marketing, management, consulting, and journalism.

The most consequential chapter.

But a chapter.

Fantasy Hero: The Solo Proof

Fantasy Hero matters more for what it proves than for what it contains.

It is Peterson’s clearest solo design credit: a 160-page fantasy adaptation of the Hero System published in 1985. It stripped away superhero-specific assumptions and built a fantasy frame around the same engine: magic, creatures, medieval skills, and genre procedures.

That proves Peterson could independently architect a complete genre adaptation.

He was not only a refiner of MacDonald’s ideas. He understood the architecture well enough to redeploy it into another genre on his own.

The work is professional, complete, and useful.

It is not a revolution.

It does not show a designer pushing beyond what the system already promised. But it shows a craftsman who knew the structure from the inside.

One game.

One proof of independent capability.

That is the solo catalog.

The Honest Assessment

The influence evidence is strong. The hard part is separating Peterson’s specific contribution from the collaboration’s total achievement.

Invention holds at 7 because the primary conceptual innovations, point-buy, effects-based powers, and disadvantages-for-points, are most strongly associated with the Champions partnership and especially MacDonald’s original mechanical spark.

Peterson helped make those ideas publishable, coherent, and extensible.

That is essential work.

It is not the same as originating the revolution.

Architecture earns an 8, Peterson’s strongest pillar, because the Hero System passes the dual test. Quality: one of the most internally consistent RPG frameworks ever built. Propagation: GURPS, Mutants & Masterminds, and others adopted structural elements.

Others did not merely notice the architecture.

They built with it.

Peterson’s solo output is thin: five years of concentrated tabletop design, sporadic returns, one clear solo design credit, and one failed major departure in Fuzion.

Professional quality throughout.

Not enough personally authored work to claim a larger solo legacy.

The Hidden Pattern

Peterson’s career reveals the difference between building and inventing.

Inventors create something that did not exist.

Builders make it real.

Both are necessary. They require different skills, different temperaments, and different evidence.

MacDonald was the inventor.

Peterson was the builder.

Together they produced something that changed how an entire industry thought about character creation, power design, and system architecture.

Apart, MacDonald moved into video games, and Peterson moved into marketing, production, and executive work.

The collaboration lasted a handful of years.

The architecture they built together has lasted more than forty.

What Remains

The point-buy framework.

The effects-based paradigm.

The disadvantages economy.

Six editions of a system robust enough that others could extend it for decades.

GURPS learning from Champions.

Mutants & Masterminds inheriting the effects philosophy.

D&D eventually offering point-buy as an option.

Peterson did not imagine the revolution alone.

He made it publishable.

He helped draw the blueprints for a house other people would live in for four decades.

That is not the same as inventing it.

The credits are honest about the difference.

It is also not nothing.

The history is honest about that too.
