AI Disclosure: This Enhanced Edition of Gateway RPG features some AI-generated artwork and layout assistance. The rules were still hand written by me and human proofread/playtested since 2017. As a one-man passion project with $0 budget, and $0 revenue gain from this game, this edition utilizes AI imagery only to provide a visually richer and cohesive experience while keeping the game entirely FREE. The original Classic Edition from 2017, featuring human-created artwork, is included as a bonus in the download files.

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.

NovArchaic is a modern-day science-fantasy tabletop role-playing game focused on identity-first character creation, a structured-but-creative action system, and fun, rewarding crafting. Character creation focuses on a character with a backstory rooted in the setting and goals that, once completed, unlock new ways to improve. All actions use a unified passive and active skill system, tied into a flexible critical-effect system. But what about the setting? NovArchaic's core setting is a world that didn't know it wasn't whole. The core reality shard is our modern world, with its cell phones and memes. Then there are fractures and other shards containing magic and monsters. Slowly, as time passes, these parts of the universe try to come back together, but it's a complicated, bloody mess.

GURPS Calculator is a free site for GURPS 4th Edition players and GMs. The calculators handle the rules people look up mid-session: collision and fall damage, demolitions, hiking distance by terrain and weather, jumping, throwing, how long it takes to learn a skill, plus a dice roller for 3d checks and damage. Each one cites its Basic Set page and runs in the browser without an account. Make an account and you can import characters from the free GURPS Character Sheet (GCS) program and play from the sheet on the site, with HP and FP tracked and attacks rolled in place. GMs can start a campaign and have their players join it. The GM Board shows the whole party’s stats and counters alongside the encounter, and Campaign Rolls shares every die roll with everyone playing. There are no ads, no analytics and no tracking. The site has been running since 2015, built by Jeff Demers and kept going by patrons and one-time donations.

The Grey League Community page is a place for players and Game Masters. The main hub is their blog which dives into the lore, cultures, religions, factions, history, and places of Greyhawk. Alongside this setting lore, the blog also explores Pathfinder 2e rules, GM tools, house rules, access to adventures, reviews, and practical ideas for running richer campaigns and worldbuilding. Whether someone is a long-time Greyhawk fan or a new arrival, a Pathfinder GM looking for inspiration, or a curious player looking for roleplay tips, The Grey League offers something of use.

Monster Card Generator is a web app by FutureHax that makes printable monster initiative tent cards for D&D 5e and the 2024 rules. Users browse a creature library, filter it by name, CR, type, size, and source, and lay out up to three cards on a US Letter sheet with a live preview. Then they print the sheet or download a PDF.  Each card folds over the DM screen. The DM sees the full stat block, with AC, HP, speed, initiative, abilities, attacks with damage dice, traits, actions, reactions, and legendary actions, and the players see the creature's art and name. Users can also build homebrew creatures with custom artwork, generate stat blocks from a plain-English description with AI, add party characters, and pick or design card themes.  The free Farsight Importer browser extension can import from D&D Beyond or Foundry VTT. Full access is a one-time $14.99 purchase or comes with the FutureHax Patreon Captain tier.
