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.

No Lime Light Productions is a YouTube channel dedicated to content surrounding Prosperon: A Bio-Cyberpunk RPG, an independent tabletop role-playing game created by No Lime Productions. The channel serves as the primary hub for official game media, instructional content, and ongoing playtest material. The channel features a variety of content formats, including how-to guides, lore breakdowns, and an extended playtest podcast. These videos are designed to support players, introduce newcomers to the game’s mechanics, and expand on the worldbuilding present in the core rulebook. Lore and Voice Work A notable component of the channel is its series of lore videos. These episodes adapt narrative material from the Prosperon core rulebook and present it in a dramatized format. Voice performances for these videos are produced using ElevenLabs, a subscription-based service that compensates voice actors for the use of their vocal profiles. This approach adds additional atmosphere and characterization to the game’s setting. Playtest Campaign No Lime Light Productions also features a long-running “solo couples” playtest campaign. The series follows the game’s creators through their sessions, capturing the story as it unfolds, the emotional moments that come with it, and the ways they push and test the Prosper system. Over time, the campaign has become a defining part of the channel, giving viewers a clear sense of the game’s tone and how it plays at the table.

Syrinscape is a revolutionary sound design application created by Benjamin Loomes and the team at Syrinscape Pty Ltd. Unlike simple music players, it uses a sophisticated algorithmic engine to create dynamic, non repeating soundscapes that react to the events of a tabletop game. It is the official audio partner for major brands like Dungeons & Dragons, Pathfinder, and Call of Cthulhu, offering hundreds of professionally produced "SoundSets" that provide everything from cinematic orchestral scores to specific monster growls and spell effects. Description Syrinscape is built on the philosophy that "Epic Games Need Epic Sound." It provides Game Masters with a powerful digital soundboard where every element of an environment is independently controlled. Instead of playing a single audio loop, the app randomly triggers individual sounds—like a distant wolf howl, a creaking door, or a tavern patron’s laugh—to create a living, breathing atmosphere. It is available as a downloadable app for offline play or as a high performance Web Player for remote sessions. System Overview & Key Features The Dynamic Audio Engine The core of Syrinscape is its ability to randomize sound samples in time and 3D space. This ensures that a "forest" soundscape never sounds exactly the same twice, preventing the listener fatigue that often comes from short, repetitive audio loops found in standard music players. One Shot Sound Effects Beyond ambient music, the app features dedicated buttons for instant sound effects. A GM can trigger a fireball explosion, a dragon screech, or a critical hit stinger at the exact moment a player rolls the dice, adding a cinematic punctuation to the narrative. Official Adventure SoundSets Syrinscape produces bespoke audio for official RPG modules. When running a major campaign like Curse of Strahd or Abomination Vaults, GMs can access SoundSets designed specifically for every room and encounter in the book, including character voices and unique environmental cues. The Web Player and Online Player For remote play, the Web Player allows players to hear the GM's audio in perfect sync through their own browsers without needing an account. It is highly optimized for low latency and high quality, making it a perfect companion for Discord based games. SoundSet Creator Advanced users with a SuperSyrin subscription can access the SoundSet Creator tool. This allows you to upload your own music and samples, mix them with existing Syrinscape elements, and build completely custom environments tailored to your specific campaign world. VTT Integration Syrinscape features deep integration with platforms like Fantasy Grounds and Foundry VTT. This allows the software to trigger specific sounds automatically based on in game events, such as a character taking damage or a trap being sprung.
