Unless you have been living under a rock, you’ll have to be aware of the turmoil within role-playing games community over Hazbo/Wizards of the Coast attempting to revoke the OGL 1.0a license which has been used for 20 or so years.

Naturally this hasn’t gone down to well 🙂
The following video gives a good run-down on the situation along with providing a link to the revised license.
