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.

Dungeons & Dragons 3rd Edition (D&D 3E) is a fantasy tabletop roleplaying game of dungeon delving and heroic adventure, published by Wizards of the Coast in 2000. It was the first edition the company released entirely itself, and the Player's Handbook went on sale on August 10, 2000, with its debut at Gen Con that month. Monte Cook, Jonathan Tweet and Skip Williams all contributed to the Player's Handbook, Dungeon Master's Guide and Monster Manual, and each then wrote one of the three books, with Tweet credited with the design of the Player's Handbook. The designers set out to simplify and declutter the whole system. "Advanced" was dropped from the title because the Basic game had been discontinued and the simpler name was more marketable, but it was still called the third edition. The system directly replaced Advanced Dungeons & Dragons Second Edition (1989). It was revised in 2003 as Dungeons & Dragons v.3.5, a deliberately small update. Description Players take on adventurers built from a race and a class, and the Dungeon Master (DM) runs dungeons, monsters and campaigns. The edition removed many of the old limits: restrictions on class and race combinations, and on level advancement for non-human characters, are gone. Combat expanded to include a grid system that supports tactical play and miniatures. The game asks a table to be comfortable with character building. Skills and feats give players more ways to customize a character than the older edition did, and the options keep growing with each rulebook. Reviewers at the time praised its art and tightly packed rules, and one called it the best combat-oriented roleplaying game available.

Advanced Dungeons & Dragons Second Edition (AD&D 2E) is a fantasy tabletop roleplaying game of heroic adventure, published by TSR in 1989 and designed mainly by David "Zeb" Cook. Work began in 1987 with a small TSR team led by Cook, and Steve Winter and Cook redeveloped the edition after Gary Gygax, who wrote the first edition, left TSR in 1985. The Player's Handbook and Dungeon Master's Guide sold over 400,000 copies in their first year, though lifetime sales fell short of the first edition, and the Dungeon Master's Guide won Origins and Gamer's Choice awards. TSR re-released the core books in 1995 with new covers, art and layouts, and the line was succeeded by Dungeons & Dragons 3rd Edition in 2000, which was revised into Dungeons & Dragons 3.5. The system directly evolved from Advanced Dungeons & Dragons First Edition (1977). It was designed to work with first edition rules, but its information was streamlined and clarified. Description Players take on adventurers drawn from a set of races and classes, and the Dungeon Master (DM) runs dungeons, wilderness and, in later years, whole settings. The edition shifted the game's feel from 1960s and 1970s sword and sorcery to medieval history and mythology, and it stressed heroic roleplaying and teamwork. Demons and devils were removed by name and renamed tanar'ri and baatezu. The second edition grew far beyond a single fantasy world. TSR added settings such as Ravenloft (horror), Spelljammer (science fiction) and Dark Sun (apocalyptic), each with its own rules supplements. The game asks a table to keep a few tables and a fair amount of arithmetic, and the many optional rules mean the DM should decide what is in play at the start of a campaign.

It's October 13th, 1999 and the world has ended. Someone, no one is sure who, let something into our world. A kind of infection or corruption that affects both the body and the mind. Animals, people, even mundane objects... all became twisted and unnatural. Some speculate it's a kind of demonic possession, others that it's an alien or even transdimensional biological weapon. In the end, it doesn't matter. The whole world fell apart, twisted from within. The survivors cling to their wretched lives in a fallen world, trying to comprehend the horrors and fend them off for just one more day. The world is in tatters, monsters roam around consuming everything they can, strange occult powers spread among the damned, and even the very air seems tainted. Perhaps the rapture happened and the survivors are being punished because they were found wanting. Perhaps this is some kind of strange terrorist attack from another world. Or maybe it's all nothing more than a cosmic accident, a tragedy of happenstance as something never intended for this world found its way in. Can you survive and fight off the horrors coming from within and without? Description October Twilight is a survival horror/dungeon crawler tabletop roleplaying game for 2 or more players. One player must take the role of the Game Master. This game assumes familiarity with other roleplaying games and so much of the basic flow of roleplaying is not explained. The game is meant to feel like a PS1/PS2 era survival horror game and a post apocalyptic survival game. Food is scarce, ammunition is scarcer, and everything is trying to kill you. In the game, your team has a safe house they come back to between excursions. The safe house lives up to it's name, being safer than exploring the ruins of the fallen world outside your door. But, you burn resources like food and water at the safe house and have to go out to find more. You'll never have enough resources to simply hole up and wait out the end of the world. Touchstones and Inspirations: Resident Evil, Silent Hill, The Walking Dead, Darkest Dungeon, and Evil Dead 2.

Forge Steel is a community-developed, locally-hosted web application and digital utility designed for Draw Steel, the cinematic fantasy tabletop role-playing game created by MCDM Productions. Developed by independent community members during the game's playtest phase, the application functions as a lightweight encounter builder and combat manager. It is specifically built to assist Directors in organizing game data and tracking real-time combat statistics during a session. Description Forge Steel serves as a digital toolkit for preparing and executing combat encounters in Draw Steel. In contrast to cloud-based alternatives, Forge Steel relies on local browser storage. This means the application does not require users to create an account or rely on external servers to save their data. All created encounters, customized monsters, and campaign notes are stored directly within the cache of the user's web browser. This architecture prioritizes data privacy, offline accessibility, and fast load times, though it requires manual file exporting to transfer data between different devices.

Genesys is a role playing system designed for flexibility and adaptability, specifically tooled to work with any setting imaginable.

With a system so adaptable and expansive you can explore every popular roleplaying genre, from classic fantasy style campaigns, to modern day detective thrillers, and even to a far off sci-fi future, Genesys doesn’t fit into any one genre of roleplaying, and instead invites players to craft their own stories with unparalleled freedom.
