Writers and other content creators have always taken inspiration from the stories they loved, even in history. Game Masters can adapt media elements that they and their players enjoy into inspiration for their campaigns. Some of the most popular media for tabletop games to build off of are television shows.
She-Ra and the Princesses of Power already resembles a TTRPG campaign in several ways so that it would fit perfectly as inspiration for one. Though the colorful and vibrant visuals are maintained throughout the entire series, the stakes steadily increase, just as they do with long-term campaigns, as the characters level up.
The show also excellently integrates high-fantasy concepts with advanced technology and space travel, steadily introducing the details as time passes. The world of Etheria could inspire beautiful, narrative-driven campaigns.
