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.
User summary:
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.).
