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.

Shadow of the Demon Lord is a grim dark-fantasy tabletop roleplaying game set during the last, doomed years before an apocalypse, designed by Robert J. Schwalb and published by his own studio, Schwalb Entertainment, in 2015 following a Kickstarter campaign.  It builds a d20-based system deliberately stripped of the modifier-stacking common to games in its weight class, replacing most situational bonuses and penalties with a single abstracted mechanic. Schwalb later returned to the same core system for a lighter, more traditional-fantasy spinoff, Shadow of the Weird Wizard, released via Kickstarter in 2023. Description Characters begin as ordinary commoners rather than destined heroes, in a world where the Demon Lord's return is already underway and survival - not glory - is the realistic goal of most adventures. The Game Master (GM) runs a setting that leans hard into body horror, corruption, and creeping dread, and the game states its demands plainly.  Characters can and do die, sanity can crack under the weight of what they witness, and doing what's necessary to survive can leave a permanent, mechanical stain on a character's soul. It's built for a table that wants D&D-adjacent fantasy combat without D&D's heroic framing - closer in spirit to grimdark fiction than epic fantasy, with character death treated as a real and fairly common outcome rather than an exception.

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.

Merak is a map maker for worldbuilders. Five kinds of map live in one document: a political map of Earth, an editable Earth with real terrain, a blank world, a fantasy map and a city board, and factions, units, labels, cities and lore carry across all of them. Land can be raised, lowered, smoothed, flattened, roughened and worn down with droplet erosion; biomes paint on top; a thin river tool cuts channels without shattering the coast. The world generator builds plates, mountain chains and weathered coastlines from a single seed, and the Planet Advisor checks whether the result could exist at all, whether rivers have anywhere to drain, whether the biomes suit their latitude. An elevation probe reads back true metres and slope, and any map can be viewed in 3D or wrapped onto a shader globe. Custom empires are drawn freehand with a lasso, and a coast mode clips the outline to the actual shoreline so borders follow the water instead of cutting across it. The arsenal and battle system has faction tinting and stacking counts, alongside commanders carrying portraits, ranks, decorations and an order of battle. Operational arrows play out as scripted advances with per-province combat. On a battle map, Fight animates the whole clash: infantry and armour close to melee under a counter system, artillery bombards from range with splash damage, aircraft strike fast and hard, and badly wounded units break off to a field hospital, heal, and return to the line. The timeline holds the progress of the map over the years. Lore notes form a small in-map wiki placed anywhere or pinned to a city, unit or flag, and linked to one another. Raster paints layers with blend modes, pressure and grain; an Asset Studio for custom symbols; flag and insignia makers; a colour studio. Finished maps exported as PNG up to 16K.

Alien: The Roleplaying Game is the officially licensed tabletop RPG of the Alien film franchise, designed by Free League CEO Tomas Härenstam with franchise lore writer Andrew E.C. Gaska, and published by Free League Publishing in December 2019. It runs on an adapted version of Free League's Year Zero Engine - the same family powering Mutant: Year Zero and Tales from the Loop - reworked specifically around the dread and claustrophobia of the films rather than open exploration. The game won the Gold ENNIE for Best Game in 2020 and has remained one of Free League's flagship lines since.
