In an FAQ post about the upcoming Harry Potter RPG Hogwarts Legacy, Warner Bros. clarified that author J.K. Rowling was not involved with the creation of the game’s story.
“J.K. Rowling is not directly involved in the creation of the game, however, her extraordinary body of writing is the foundation of all projects in the Wizarding World,” says WB in response to a question about J.K. Rowling’s involvement. “This is not a new story from J.K. Rowling.”
Subsequent answers posted throughout the FAQ reveal more about Rowling’s involvement or apparent lack thereof. For instance, the FAQ notes that developer Portkey Games will be “remaining true to J.K. Rowling’s original work” but intend to “chart new territory by creating fresh ways for fans to immerse themselves in the wizarding world.”
Along those same lines, it’s later mentioned that the game is “inspired by J.K. Rowling’s Wizarding World” and that the games are “anchored in Wizarding World lore.” Yes, they used the word “games” as in plural. Later on, WB clarifies that Portkey Games intends to “create a variety of new and immersive gaming experiences that are all inspired by J.K. Rowling’s Wizarding World.” There again, they make sure to note that “these experiences have not been written by J.K. Rowling and will not be direct adaptations of the books or films.”
