The Open Game License (OGL) is a legal framework that allows creators to use certain game mechanics and content from specific role-playing games, such as those from Dungeons & Dragons. It was introduced by Wizards of the Coast in 2000 to encourage third-party publishers to create compatible materials, expanding the gaming community and enhancing creativity. Under the OGL, creators can publish their own game content while adhering to specific guidelines. This license promotes collaboration and innovation, enabling a diverse range of products, from adventure modules to new game systems, all while maintaining respect for the original intellectual property.
