Chuubo's Marvelous Wish-Granting Engine
The Chuubo's Marvelous Wish-Granting Engine RPG (just "Chuubo's" for short) is unique, original, and fun — a diceless, narrative system that captures the bright and dark tones of modern anime (especially Studio Ghibli) and cartoons like Adventure Time or Steven Universe. I recommend it highly. These are some of the resources I've contributed to or created:
A Guide for New Chuubo's Players
An easy-to-understand introduction (also available on the Chuubo's wiki
)

Chuubo's Miraculous Arcs
Updated for the most recently shared draft of the Book of Golden Hours
Chuubo's Character Options
Some canonically supported backgrounds and "races", plus a list of Magical and Superior Skills
Chuubo's Form-Fillable Character Sheets (PDFs)
Intentionally Vague Map of "Town" (PDF)
Shows how Town is laid out without committing to a detailed map

In addition, I've been musing on how to use the Chuubo's rules to do a "Nobilis Fourth Edition" over at The Marvelous Nobilis Engine.
