Arkham Horror: The Roleplaying Game

Ouroboros: Age of Drowning is an original tabletop roleplaying game with its own setting and unique narrative-focused dice-pool system. Set in a dystopian world after the Meteor Fall, Ouroboros: Age of Drowning combines mystery, forbidden Alchemy, and surreal horror. The technocratic Clockwork Faction enforces a victorian New Order from its industrious Domed Cities, while rising seas consume the world beyond. As members of a League, you make discoveries in a world where Reality is unstable. Investigate strange phenomena, confront Factions with competing agendas, and encounter Aetherika, spirits, folklore made real, and horrors from the Otherworld. Venture into Dreamscapes, where Surreality blurs the boundary between worlds, and confront the Dark Thoughts within yourself as your Shadow grows. The game uses a dice-pool system designed around Traits, Specializations, and Focuses, giving characters different ways to approach problems rather than reducing them to a handful of broad attributes. Investigation, social maneuvering, survival, combat, occult practices, Dreamscapes, and forbidden Alchemy are all handled through the same core system.

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.

Achtung! Cthulhu is a pulpy World War II horror tabletop roleplaying game in which Allied and resistance agents fight a secret war against Nazi occultists and the Cthulhu Mythos. It was created by Chris Birch and published by Modiphius Entertainment, which launched the setting in 2012 as an adventure series for Call of Cthulhu, with versions for other systems announced. The 2d20 edition, with rules designed by Nathan Dowdell, launched on March 9, 2021, as a standalone game with a Player's Guide and a Gamemaster's Guide. The 2d20 edition replaced the earlier versions of Achtung! Cthulhu, which were written for other systems, and uses the same 2d20 system as Dune: Adventures in the Imperium. Description Players take on soldiers, spies and resistance fighters in a war where the real enemy is behind the enemy. Campaigns run from 1939 to a confrontation in Antarctica in 1946, with scenarios in places such as occupied Czechoslovakia and Dunkirk. The Gamemaster (GM) runs the war, the Black Sun cultists and the creatures they command, including undead, Deep Ones and a Shoggoth. The tone leans towards action rather than dread. The supernatural is a threat to be overcome, at least for a while, which sets it apart from the more fatalistic horror of Call of Cthulhu. The game asks for a table that wants a combat-heavy war story with a thin layer of cosmic horror.

VVD is a visually driven world-building and campaign management platform launched in 2024. Created by an independent developer, it positions itself as a streamlined, "distraction-free" alternative to complex wikis like World Anvil. In 2025, the platform gained massive popularity on social media for its "clean UI" and its strict No-AI pledge, promising that all art and assets on the platform are created by human artists.  Description VVD is built for the "sparks of inspiration." It uses a card-based system to organize NPCs, locations, and magic items, allowing users to connect them visually through an interactive graph. Unlike traditional folder-heavy organizers, VVD feels like a digital corkboard or a personalized Wikipedia that prioritizes aesthetics and ease of use. It is a web-based tool, meaning it requires an internet connection, but it is highly optimized for mobile devices, making it a favorite for GMs who need to jot down world-building notes on the go.

Tale of the Manticore is a hybrid between a dark fantasy audio drama and a solo Dungeons & Dragons RPG. The dice make all the important decisions and, as a writer, my job is to interpret them and tell their story. Part fiction, part game, it’s the story where ”Chaos rolls.” Links taleofthemanticore.com - Official website youtube.com - Youtube channel spotify.com - Spotify feed

Kenku FM is a specialized high fidelity audio sharing application designed specifically for tabletop gaming over Discord. Created by the developers of Owlbear Rodeo, it was released in 2022 to provide a reliable, high quality alternative to traditional Discord music bots. It functions as a standalone virtual browser and media player that acts as a bridge, streaming audio directly from a user's computer into a Discord voice channel with minimal latency and superior sound quality. Description Kenku FM solves the common problem of sharing immersive music and sound effects during online TTRPG sessions. Instead of relying on buggy cloud bots that often face copyright shutdowns, Kenku FM runs locally on the Game Master's computer. It allows the GM to log in as a "Bot" on their own Discord server, giving them total control over the audio stream. It is a lightweight, open source tool that treats audio as a vital part of the storytelling toolkit rather than an afterthought. System Overview & Key Features Integrated Web Browser Kenku FM features a built in browser designed specifically for audio. You can open tabs for YouTube, Spotify, Tabletop Audio, or Syrinscape and stream the audio directly into your Discord call without needing to share your screen or lose audio quality. Local File Playback The app acts as a robust media player for your personal sound library. You can create playlists from your own MP3 and WAV files, allowing for instant playback of specific combat themes or environmental ambiance stored on your hard drive. Soundboard Functionality Users can set up a custom soundboard within the interface. This allows a Game Master to trigger one shot sound effects like sword clashing, explosions, or monster growls at the perfect narrative moment with a single click. Stream Deck Integration For power users, Kenku FM offers a dedicated plugin for the Elgato Stream Deck. This allows the GM to control volume, skip tracks, and trigger soundboard effects using physical buttons, keeping their hands free to manage the game and maps. High Quality Audio Engine By using a dedicated bot connection rather than standard screen sharing, Kenku FM maintains high bitrate stereo audio. This ensures that orchestral scores and subtle environmental textures sound exactly as intended for every player in the voice channel. Open Source and Privacy The software is open source and runs locally, meaning it does not track your data or rely on external servers that can be shut down. You own the software and have total control over the bot account you create to facilitate the stream.
