Shadowdark RPG (2023)

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.

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.

Back in 2015, I discovered S. John Ross’s classic 1993 game, Risus: The Anything RPG. It was free, modular, ultra-flexible, and simple to pick up, but as I played more TTRPG's like DND5e, I missed the iconic d20 and the drama of critical hits and misses. I created GATEWAY RPG to capture that same beginner-friendly spirit while bringing back the thrill of the twenty-sided die and being able to use it for any setting. Whether you are running quick one-shots, playing standalone adventures, diving into solo sessions, or modularly introducing advanced rules as your group learns, GATEWAY adapts seamlessly to your table. GATEWAY RPG and Aurican's Lair are a Not-For-Profit Tabletop Roleplaying Game publisher.
