An "Open Game" refers to a type of game that allows players to freely create, modify, and share content. This concept is often associated with tabletop role-playing games, video games, and board games, where rules and settings can be adapted by the players. The flexibility encourages creativity and collaboration among participants. In the context of tabletop gaming, an example of an open game is the Open Game License (OGL), which permits creators to use certain elements from established games like Dungeons & Dragons. This fosters a diverse range of new adventures and expansions, enriching the gaming community.
