GATEWAY: The Free d20 Tabletop RPG


The GATEWAY RPG Tabletop System is a Free, rules-lite, easy to learnfast-paced, and universal D20 Roleplaying Game framework that is perfect for introducing new players to the hobby of tabletop RPG’s. This system allows for any theme or setting, from Fantasy to Cyberpunk, from Horror to Noir, or whatever your imagination can create.


GATEWAY’S simple rules are based around similar mechanics from the 5th Edition of “The most popular roleplaying game in the world”.  It is easy for new players to learn the rules, go on an adventure in a short period of time, and is the perfect “gateway” to other tabletop RPG’s. The open genre even provides a great format for “One Shot” adventures with your fellow veteran players and Game Masters. Alternatively, long term on-going campaigns are possible by using Gateway’s “Advanced Rules Variant” or by simply incorporating (or even replacing) with other d20 systems such as D&D, Pathfinder, Star Wars D20, etc.

“The Missing Princess of Thornfall”

The Missing Princess

The Dark Ravens Adventurers Guild never turns down a desperate lord and lady in need of finding their missing daughter. Your group finds themselves following up such a contract in the town of Thornfall. She apparently was last seen playing near the village wall. Did she stray over the wall and get lost, was she kidnapped by a rival lord for ransom, or did something darker come out of the woods to claim an innocent life? Your party must find out.

List of Monsters and NPCs from Converted Materials

Compiled some 3rd Party resources in order to make some simple conversions of the monsters and NPCs into GATEWAY. These include D&D5e, Pathfinder, Star Wars, Shadowrun, and Starfinder.
