Risus: The Anything RPG is a universal, rules-light tabletop role-playing game designed by S. John Ross and published by Cumberland Games & Diversions. Originally released in 1993, with its definitive version 2.0 published in 2013, the system was created as a high-velocity framework to run casual, humorous, or completely impromptu gaming sessions across any narrative genre. Description Risus prioritizes improvisational storytelling and minimalist mechanics over granular simulation or tactical grid combat. Instead of tracking traditional numeric attributes, skills, or rigid character classes, characters are defined entirely by broad cultural or narrative tropes called "Clichés." The game operates on a high degree of system abstraction, utilizing a completely unified conflict engine where physical combat, intense debates, artistic competitions, and legal battles are resolved using the exact same mathematical pipeline. While frequently utilized for comedic play due to its loose restrictions, the system's structural logic allows it to be scaled for serious or dramatic campaigns.

Mothership is an action-packed mixture of sci-fi and horror themes, combined into a streamlined gaming system about surviving in the cold, deadly vacuum of space while everything around you is trying to kill you. All at the same time as you are fighting (or fleeing from) alien creatures who aren't there to make any new friends. Chaos. It was published by Tuesday Knight Games and released in 2024.  It is a survival horror system designed for one-shots and campaigns, inspired by classics like Alien, Event Horizon, and Pandorum. Famous for its streamlined ruleset and award-winning graphic design that prioritizes ease of use at the table. The game, at the same time simplistic and streamlined in design, will challenge the characters at all times, allowing the game to focus on the storytelling and less on having complicated rules. The system it is inspired by is Old School Renaissance Description In Mothership, players take on the roles of blue collar workers in space, such as Teamsters, Scientists, Androids, and Marines. You are not powerful or heroic soldiers; you are vulnerable humans trapped in high pressure environments with alien monsters, failing life support systems and the crushing weight of corporate greed. The game is designed to be fast-paced and unforgiving, where the primary goal is not to win, but often enough - to survive. System Overview & Key Features d100 Percentile Resolution In the core of the game system is the d100 percentile system. Roll two d10 dice and get a number from 00 to 99. Success means rolling a lower result than your character's appropriate stat or skill for the task. Rolling a double, like 11, 22, or 33, is considered a critical success if it succeeds or a critical failure if it fails. Rolling low is the target for survival. Stress and Panic As characters encounter horrors or suffer trauma, they accumulate Stress. When a character experiences a terrifying event or rolls a critical failure they must make a Panic Check. The more Stress they have, the more likely they are to suffer a catastrophic mental breakdown, ranging from a heart attack to a violent psychotic break. The Save System Instead of a long list of saving throws, characters have four primary Saves: Sanity, Fear, Body, and Armor. These are used to resist different types of potential trauma. Fear saves are rolled to keep your cool under pressure, while Sanity saves represent your ability to process alien truths without losing your mind (think lovecraftian horrors). Class Based Skills The game features four distinct classes. Marines are obviously combat focused, Teamsters are pilots and laborers, Scientists are experts in medicine and biology, and Androids are cold calculating, yet efficient machines. Each class has it's unique starting stats and specific triggers for when they gain or lose Stress, which is based on their personality. Lethal Combat and Healing Combat is extremely dangerous and often a last resort. Weapons are likely to deal potentially excessive damage when compared to a character's total healthpool. Healing will be slow and require resources that are hard to come by in the middle of the constant crisis, making every injury feel like a significant threat to the character's chances of making it out alive. Deadly Ship-to-Ship Combat The game includes a streamlined system for starship encounters. Ships have their own stats and modules that are likely to be damaged during a fight. Players must work together to manage various roles and stations, like Engineering or Piloting, to keep the ship's hull from breaching while under fire or fleeing from cosmic anomalies.

Basic Roleplaying is the venerable "D100" engine that has powered Chaosium’s greatest hits for over four decades. Originally appearing as a slim booklet in 1980, it was most recently revitalized as the Basic Roleplaying: Universal Game Engine in 2023. In 2026, it stands as one of the industry's most important open-source platforms, released under the ORC License, allowing independent creators to build and sell their own games using its legendary, time-tested mechanics. Description BRP is a "genre-neutral" toolkit that discards character levels and rigid classes in favor of a pure skill-based system. Whether you are playing a Bronze Age warrior, a 1920s detective, or a futuristic mech pilot, the core experience remains the same: your character is defined by what they can do. Because it uses percentages (e.g., "I have a 65% chance to climb this wall"), it is widely considered the most intuitive and "transparent" RPG system for new players to understand at a glance. System Overview & Key Features The Universal D100 Engine Every action is resolved by rolling two ten-sided (d10) dice to get a result from 1 to 100. If you roll is equal to or under your skill rating, the action is deemed a success. This approach simplifies the mechanical process of the game, as there are no complex tables to keep track of and compare to decypher whether it is a success or failure. Organic Character Growth There is no "Experience Points" system in the traditional sense. Instead, when you succeed in using a skill, you mark a "Skill Check" on your character sheet. At certain stops in the game/story, the player rolls to see if the character improves in those skills, meaning your character evolves based specifically on the actions they performed (and succeeded at) during the game. Modular Rule Design The Universal Game Engine is designed with variations and systems to choose from. GMs can choose whether they prefer to just use "Hit Points" or add a more detailed wound system with "Hit Locations" for more realistic tactical consequences. Systems for Magic, Sorcery, Mutations, or Superpowers (depending on the setting) can be added, instead of being baked in the core mechanics, ensuring the mechanics always fit the theme of the game. Deadly and Tactical Combat BRP combat is grounded and dangerous. Unlike high-fantasy games where adventurers have a vast health pool, a single strike of a sword or bullet in BRP can be fatal. This encourages players to think creatively and use mechanics and terrain to their advantage. Talking their way out of situations is often seen as more reasonable (and survivable), than just treating every conflict as a forced combat situation. The ORC License Revolution By introducing to the Open RPG Creative (ORC) license, BRP started a wave of third-party "Powered by BRP". This has expanded the system into new genres like Cyberpunk, Wuxia, and Cozy Fantasy, all supported by a single, unified ruleset and system, compatible with most themes. Compatibility with "The Big Three" Because the core mechanics have remained the same since the beginning, a monster or spell from a 1980s supplement is almost always compatible with the modern 2026 engine. This gives GMs access to one of the largest libraries of pre-written adventures in tabletop gaming, spanning Call of Cthulhu, RuneQuest, and Pendragon.

Wanderhome is a pastoral fantasy role-playing game about traveling animal-folk, the world they inhabit, and the way the seasons change. It is a game filled with grassy fields, mossy shrines, herds of chubby bumblebees, opossums in sundresses, salamanders with suspenders, starry night skies, and the most beautiful sunsets you can imagine. You might be a tamarin who dances with small and forgotten gods, a leporine mail carrier who relies on moths to get packages where they belong, a little lizard with a big heart and a mysterious past, or a near-endless number of other thrilling possibilities. No matter what, we’re always travelers—animal-folk who go from village to village and get to see the length and breadth of all the world of Hæth. The seasons will change as we play, and we will change with them. Description Wanderhome is built on the Belonging Outside Belonging engine by Avery Alder and Benjamin Rosenbaum. That means there’s no dice, no math, no Game Masters, and no complicated rules. It’s all about getting you into game as smoothly as possible, and filling your imagination with richly developed worlds and evocative text. The game is designed for any length of session, and with any number of folks. Whether you’re sitting down with a couple of friends for a cozy after-dinner hangout or throwing a party for a decade-long campaign, Wanderhome always has space for your experiences and needs. /images/general-media/1779960617_hvwl1UPt.webpThe World of Hæth Wanderhome is set in the wholly original fantasy world of Hæth, inspired by the works of Brian Jacques, Tove Jansson, and Hayao Miyazaki. The game hints at and builds a mythological language around forces like the bitter King of the Floating Mountain, the Lily Rebellion, the Slobbering God and the blade that killed her, and the fall of the great dragons of old, but refuses to elaborate or define them—leaving that exercise to the players through the journey itself. Instead, Wanderhome is focused on the lives of ordinary people, and the world that exists for farmers, merchants, and crafts-folk. Wanderhome is a world filled with animal-folk and their buggy livestock. Unlike many worlds with animal-folk, there is no morality or judgement ascribed to the various animals of Hæth—a snake is just as capable of being a kindly farmer as a rabbit, and you can’t assume much about someone based on what animal they are. You might find a fluffy shepherd with a herd of bumblebees, a shrewish merchant riding a stag beetle the size of a house, a lonely fox riding a grasshopper from place to place, or a praying mantis that hangs out in a gecko’s pocket.

Jim Henson's Labyrinth: The Adventure Game (commonly referred to as The Labyrinth RPG) is a whimsical, rules-light tabletop role-playing game designed by Ben Milton and Jack Caesar, and published by River Horse Games in 2020. Officially licensed and based on the 1986 cult classic musical fantasy film Labyrinth, the system is explicitly engineered to accommodate both veteran role-players and complete beginners. It trades complex simulationist mechanics for streamlined puzzle-solving, theater-of-the-mind exploration, and improvisational narrative problem-solving. Description The Labyrinth RPG drops players directly into the shifting, surreal dreamscape of Jareth the Goblin King’s maze. The overarching premise mirrors the movie: players must navigate the treacherous, puzzle-filled environment to reach the Goblin City and rescue someone or something of immense personal value before the clock strikes thirteen. The game is fundamentally non-violent; conflicts are structured around riddles, social manipulation, environmental obstacles, and trickery rather than traditional weapon combat or health point attrition. The physical book itself functions as a luxury artifact, famously incorporating a hollowed-out spine that contains a set of custom six-sided dice and ribbon bookmarks to facilitate instant play.

Old-School Essentials is a Dungeons & Dragons B/X retroclone designed by Gavin Norman and published by his own studio, Necrotic Gnome, first released in 2019. It doesn't reinvent the 1981 Basic/Expert D&D rules so much as reorganize them: rather than hunting across four different chapters just to build an elf character, every rule on a given topic now lives on a single two-page spread, with modern layout and clarity layered over mechanics that are otherwise untouched. Since launch it's become something close to the flagship rulebook of the Old School Renaissance - clean enough to hand a brand-new player, and 100% compatible with four decades of B/X-era modules and third-party adventures.
