Radiance RPG: A Complete Role-Playing Game
in Tesla's Gilded Age of Electrotech


Radiance RPG is a d20-lite game. It is also a philanthropic project. We offer the entire 284-page illustrated Radiance Players Guide as a free download. It wasn't cheap or quick to craft, but we want to share it!

Radiance RPG focuses on the late 19th and early 20th century. That said, it supports any genre—guns, monsters, and/or magic—up to (but not including) today's world. It blends several editions of the world's most popular fantasy RPG. If you've played a d20-based game, you will find familiar terms and situations with nice improvements. For example, a single combat needn't take 3 hours! Scheming to marry off a wealthy princess may prove just as vexing as defeating a dragon. Creating and updating characters and adventures has never been easier in a d20 like system. GM's in will delight over the plethora and usefulness of NPCs, while players will enjoy flexibility and simplicity of growing the character of their heart's desire.
