Gateway RPG: The FREE Universal Bridge to Tabletop Roleplaying Adventure

Gateway RPG is a free, rules-lite d20 framework designed for speed, simplicity, and total creative freedom. Built on the familiar chassis of 5th Edition mechanics, it serves as the ultimate "bridge" to the world of tabletop RPGs.

Whether you’re introducing friends to their first session or running a high-octane one-shot for veterans, Gateway gets you playing in minutes, not hours. From neon-soaked Cyberpunk streets to grit-filled Noir alleys, if you can imagine it, Gateway can run it.

Use of AI Art Transparency Disclaimer:

GATEWAY RPG is a $0-budget solo passion project. To address past feedback regarding "disjointed" art styles, the Newer Editions utilize AI tools to provide a consistent, cinematic visual experience while keeping the game 100% free.

However, for those who prefer traditional human-led creative works, a "Throwback Edition" is included. This version is 100% AI-Free and features curated illustrations from Axebane Games, Sine Nomine (Godbound/Starvation Cheap), Dire Rugrat, StockArt, and independent artists. 

The rules are 100% my own work. I've provided different art options to address community feedback and personal preferences, but the mechanics remain untouched. Ultimately, it’s your game so you decide if the art makes a difference to your experience.
