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.

Salvage Union is a RPG set in a Post-Apoc world where MegaCorps rules pockets of civilization and nomads on giant 'Crawlers' comb the wastes for 'salvage'. Players are part of the 'Salvage Union', on one of these roaming Crawlers and deploy out in jury-rigged Mechs to collect salvage and investigate their ruined world. Description Playing Salvage Union means playing a crew of salvager mech pilots living aboard a massive, mobile home base called a Union Crawler, scavenging a corporate-ravaged wasteland for scrap to keep their community alive. Beyond raiders and rival scavengers, threats include monstrous Bio-Titans, alien Meld, and the Corpos who still control most of the world's remaining resources. Much of the game's appeal comes from its two-layered loop: narrative exploration and salvaging runs outside the mech, and tactical, resource-managed mech combat once things go loud, tied together by a deep crafting system that lets pilots build and refit their machines from scavenged parts between missions.

Dolmenwood is a fantasy adventure RPG designed by Gavin Norman - also the creator of Old-School Essentials - published by his studio Necrotic Gnome in partnership with Exalted Funeral Press, following a hugely successful Kickstarter that launched in August 2023.  It's built on a streamlined, customized version of the Old-School Essentials rules, but stands as its own complete game rather than a supplement, growing out of Norman's self-published Wormskin zine, which he'd been quietly developing since 2015. The game went on to win four ENNIE Awards, with its complete retail release - three core books, four adventure scenarios, a supplement, and a referee's screen - arriving through 2024 and 2025.

HackMaster is a crunchy, old-school fantasy tabletop roleplaying game published by Kenzer & Company, created by Jolly R. Blackburn and David Kenzer. It began as a fictional game, a parody of Dungeons & Dragons played by the characters in Blackburn's comic strip Knights of the Dinner Table, and became a real product when the comic's fictional third edition turned into the published Fourth Edition in 2001. That edition won the 2002 Origins Award for Game of the Year 2001. HackMaster Fifth Edition followed in 2011, bringing a Player's Handbook and Gamemaster's Guide, and the line has since grown to more than forty add-ons and supplements. Kenzer and Company announced a 25th anniversary edition, HackMaster XXV, in March 2026 through a Kickstarter campaign. The Fifth Edition directly evolved from HackMaster Fourth Edition, which is a custom system derived from Advanced Dungeons & Dragons (AD&D). Description Players create characters from a race and a class, as in the older editions of Dungeons & Dragons, in a low-magic world that reads as strongly old-school. The default setting is the Kingdoms of Kalamar. The Game Master (GM) runs combat, exploration and the consequences of both, and the game's rules back up a harder, more simulationist style than the parody that started it. The game asks a table to accept a lot of detail. The rules are described as crunchy, with many optional combat moves and fighting styles and wound-by-wound healing that takes real time. It suits groups who enjoy knowing exactly how a fight works and don't mind reference tables, and it is a poor fit for anyone who wants a quick, rules-light evening.

Ishanekon: World Shapers is the (probably) biggest free Indie TTRPG with over 2,500 character options. It has been mainly developed by Jan Luyken, aka Blaze Reason, with the aim of creating a game that can compete (if not surpass) the current biggest games on the market while remaining affordable for anyone. With its easily adaptable rules and wide range of options, from beginner-friendly to highly complex, it is designed to satisfy the needs of almost any story and play style. Description From epic fantasy and sci-fi to mundane humans facing everything from common threats to cosmic horror, Ishanekons: World Shapers’ modular design lets you easily adjust the rules to help you experience your stories. This game is designed with the idea that you bring the flavor, and the mechanics help you bring it to life. The 10 Archetypes with over 200 Sub-Archetypes, 1000+ Abilities, 600+ Talents, 300+ items and upgrades, and more allow you to build anything from a simple cat to a city-destroying kaiju. Role and complexity filters let you find what you need quickly while helping you avoid those features that might be too overwhelming for your liking.

Owlbear Rodeo is a "no-frills," browser-based virtual tabletop that prioritizes speed and ease of use above all else. Originally launched in 2020 as a simple image-sharing tool, it evolved into version 2.0, transitioning to a cloud-based subscription model while maintaining its "pick-up-and-play" spirit. It is the premier choice for GMs who prefer theater-of-the-mind play or quick tactical skirmishes without the heavy automation of larger platforms. Description Owlbear Rodeo is the digital equivalent of a dry-erase battle mat. It does not try to be a video game; instead, it provides a shared canvas where you can drop a map, throw down some tokens, and start rolling dice in under a minute. It is famous for requiring no player accounts. The GM simply creates a room and sends a link. While it has added advanced features like dynamic fog and extension support, it remains the most lightweight and mobile-friendly VTT on the market.
