GATEWAY - The d20 Tabletop Roleplaying Game


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 role-playing games. 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 RPGs. The open genre even provides a great format for "One Shot" adventures with your fellow veteran players and Game Masters.

Alternatively, longer term campaigns are possible by using Gateway's "Advanced Play Variant" or by simply incorporating rules from other d20 systems such as D&D, Pathfinder, Star Wars d20, Call of Cthulhu d20, etc. You can even move your adventure over completely to those rulesets.

This rule system includes the following:

  • 16 Pages of Rules for Players and a Game Master's Section
  • 1 Page Quick Reference Sheet to be used during gameplay
  • 1 Page Character Sheet (Printable or Form Fillable Options!)
  • Formatted in an easily accessible and printable PDF
  • Core Rulebook now en Español!

Brand New Update

Advanced Play Rules Variant and Advanced Character Sheets have been added to this product! The original rulebook has it's own single page of rules and form-fillable character sheets to support gameplay. This variant opens up more customized and balanced characters for longer-term play. Also, download the free high fantasy beginner module "The Missing Princess of Thornfall".

"a lot of the basic d20 rules seen in popular RPGs such as Dungeons & Dragons®, Pathfinder®, GURPS®, etc."


GURPS does not use "d20 rules". Or even twenty-sided dice, in any fashion at all. You aren't even trying to roll above a target number!

Hello Gateway Folks! Do you have any guidance on converting DnD 5e & D20 Characters (especially D20Modern/Future) to Gateway RPG? Many thanks.

Files have been fixed. I believe it was the Zip File that caused the hiccup. Enjoy!

Just wanted to say thanks to everyone who has taken their time to download my humble little Indie RPG. It has reached 2000 downloads today and 4.5 Stars out of 5 after being released a little over a year ago. I am humbled by you all and hope to see more people get into the hobby by using GATEWAY. Cheers! :-D

Product Information

Original electronic
Scanned image
These products were created by scanning an original printed edition. Most older books are in scanned image format because original digital layout files never existed or were no longer available from the publisher.

For PDF download editions, each page has been run through Optical Character Recognition (OCR) software to attempt to decipher the printed text. The result of this OCR process is placed invisibly behind the picture of each scanned page, to allow for text searching. However, any text in a given book set on a graphical background or in handwritten fonts would most likely not be picked up by the OCR software, and is therefore not searchable. Also, a few larger books may be resampled to fit into the system, and may not have this searchable text background.

For printed books, we have performed high-resolution scans of an original hardcopy of the book. We essentially digitally re-master the book. Unfortunately, the resulting quality of these books is not as high. It's the problem of making a copy of a copy. The text is fine for reading, but illustration work starts to run dark, pixellating and/or losing shades of grey. Moiré patterns may develop in photos. We mark clearly which print titles come from scanned image books so that you can make an informed purchase decision about the quality of what you will receive.
Original electronic format
These ebooks were created from the original electronic layout files, and therefore are fully text searchable. Also, their file size tends to be smaller than scanned image books. Most newer books are in the original electronic format. Both download and print editions of such books should be high quality.
