A Very Kid-Friendly RPG
In Do the players take on the role of pilgrim monks who journey around their world solving problems. Interestingly, despite the strong Wuxia feel of the setting, they do this without beating people up. This emphasis on non-violent resolution is part of Do's kid-friendly design. It's intentionally designed to be a game you can safely play with your kids and use to introduce kids to the tabletop RPG hobby.
