Show HN: Project Polyhedral an open and free, drop-in, D&D 5e replacement

Project Polyhedral is a work-in-progress, but I thought I would share its current draft here in case anyone was interested. The project is open source and licensed under CC-BY.

The idea for Project Polyhedral began with all of the drama around Wizards of the Coast's move to deauthorize the OGL 1.0a and replace it with a non-open OGL 1.1.

I've written a few rule sources for TTRPGs over the years (none of them published, one of them is a campaign setting I'm trying to publish and that was targeting OGL 1.0a) and took this opportunity to revisit some of those and try to create an open interface to D&D 5th Edition.
