[%] is a role-playing system I've been working on for a little over three years now. It has been tested, tweaked, retweaked, modified, scrapped entirely, rebuilt from the ground up, and it is now available in a compact 28-page manual. I'm not going to say it's the future of tabletop role-playing, but it might be. I wouldn't know, I'm not an authority on such things.
It was an attempt to create a system that could manage the balance between narrative-heavy, ultra-lite systems and harder, more mechanical games.
