Rubery Roleplayer Edition
From the introduction:
Welcome to The Unofficial Elder Scrolls Role-playing Game! Known as the UESRPG for short, this is a fan made role-playing game designed for play in the Elder Scrolls setting.
Rather than attempting to focus on a particular era or region within The Elder Scrolls setting, we have chosen to take a “toolbox” approach. This means that instead of using a specific story, location, time, or place as the focus of the game, we have provided a set of tools to allow players and their game master (GM) to work together to create their own adventures in the world of The Elder Scrolls.
The Unofficial Elder Scrolls Roleplaying Game Core Rulebook - Rubery Roleplayer Edition primarily is a cosmetic revision "fork" of The Unofficial Elder Scrolls RPG (3rd Ed.).
