Worth noting that for people who aren't comfortable with the PbtA "license," Dungeon World was released under a Creative Commons license and should be enough of a base for anyone who wants to write a PbtA game using a formal license. See https://github.com/Sagelt/Dungeon-World, which is the GitHub of one of the authors.
