The weird little yellow book that changed everything is spawning a revolution in tabletop RPGs
Since its explosive debut in April 2020, Mörk Borg has become more than just a successful RPG—it’s transformed into an entire ecosystem of games built on its revolutionary rules-light engine. What started as an eye-catching curiosity at retail conventions has evolved into one of the most influential game systems in modern tabletop gaming, inspiring creators worldwide to adapt its brutal simplicity across genres from cyberpunk to pirates.
The Unexpected Success Story
The impact of Stockholm Kartel’s creation can’t be overstated. At GAMA Expo 2020, this “weird little yellow book” drew more attention than established titles from major publishers. Industry veterans who witnessed its debut admit they never could have predicted the cultural phenomenon it would become. The game’s success has spawned countless modules, adventures, and now an entire family of games using the same elegant d20 engine.
The weird little yellow book probably got the most attention at that event. Had we known then what this book would do for the industry, we probably would have said you were crazy
Honorable Mention: When Miniatures Meet Mörk Borg
Forbidden Psalm by KRD Designs deserves special recognition. While not technically an RPG, Kevin Rahman’s miniature skirmish game brilliantly adapts the Mörk Borg engine for tactical combat. Available in both softcover (40), it offers a miniatures-agnostic experience that maintains the system’s signature brutality. The expansion “Forbidden Psalm: The Last War” adds even more variety to this innovative hybrid.
#5: Vast Grimm - Space Horror Perfected
Vast Grimm by Infinite Black represents one of the first successful genre translations of the Mörk Borg system. Created by Brian Colin and Ross Brandt, this sci-fi adaptation maintains the in-your-face design aesthetic while transplanting the doom and gloom to the cold vastness of space. For those who prefer cosmic horror to death fantasy, this offers the same rules-light experience with a futuristic twist.
#4: Frontier Scum - The Weird Wild West
Frontier Scum from Games Omnivorous brings the Mörk Borg engine to an acid western setting. Designer Karl Stjernberg created something unique—a book that feels like an actual relic from its own setting, complete with exposed binding and treated cardboard covers. The game features one of the best included adventures in any Mörk Borg system game: “The Organ Trail,” a train-based scenario that showcases the system’s versatility.
The attention to physical design sets Frontier Scum apart. Unlike other games that simply adapt the rules, this feels like an artifact that could have been pulled from the game world itself. Stockholm Kartel themselves praised its implementation of their engine, playing it at conventions and recommending it to fans.
#3: CY_BORG - Corporate Dystopia Unleashed
The original team returns with CY_BORG, a cyberpunk evolution that doubles the content of the original Mörk Borg. Christian Sahlén and Johan Nohr prove their system’s adaptability by successfully translating their doom-metal fantasy into a neon-soaked corporate hellscape. The book maintains the confrontational design philosophy while adding layers of complexity appropriate for its high-tech setting.
Despite being nearly twice as thick as the original Mörk Borg, CY_BORG never feels bloated. Every page drips with anti-corporate rage and cyberpunk attitude, making it the definitive rules-light option for those wanting to rage against the machine without getting bogged down in complex netrunning rules.
#2: Pirate Borg - Maritime Mayhem
Pirate Borg by Limithron represents independent creativity at its finest. Luke Stratton’s maritime adaptation could easily be mistaken for an official Stockholm Kartel product, matching their quality while adding naval innovation. The inclusion of ship combat rules shows thoughtful expansion of the base system rather than mere reskinning.
The sheer amount of content packed into Pirate Borg impressed even jaded industry observers. Every review reveals new details and systems that enhance the pirate experience without sacrificing the elegant simplicity that defines Mörk Borg games.
#1: Death in Space - The Perfect Evolution
Death in Space stands as the pinnacle of Mörk Borg system design. Created by Carl Niblaeus and Christian Plogfors, this sci-fi masterpiece balances accessibility with the signature chaos of its parent system. The foil-treated cover and hub creation system demonstrate evolution rather than simple adaptation.
If you love sci-fi RPGs, you love rules-light systems, you love everything that makes Mörk Borg special—this game is so beautiful
What sets Death in Space apart is its ability to maintain the Mörk Borg DNA while creating its own identity. It’s chaotic but readable, brutal but fair, and manages to capture the existential dread of space exploration without overwhelming players with complexity.
