Fantaji Universal Role-Playing System

From the introduction:

The Fantaji Role-Playing System is a tabletop role-playing engine designed with three goals: To maximize creative input from players on every turn, to reward tactical play and strategic problem-solving, and to direct unique characters along personal and communal story arcs with engaging climaxes. Hefty aims? Maybe. But if that sounds good to you, then this is your game. Fantaji offers all the tools you need to play your game in your world. Whatever your story, this book will help you build the system and the setting perfect for you. Of course, it also works right out of the box!
