While there are no more seasons planned for the original series, several spin-offs and prequels are in various stages of development, including:
* House of the Dragon: A prequel series focusing on the history of House Targaryen, already released and renewed for a second season.
* Other potential spin-offs: There are several other spin-offs in development, but details are scarce.
It's important to differentiate between the original Game of Thrones and the spin-offs. The original series is complete with 8 seasons, while the spin-offs are separate, potentially adding more content to the world of Westeros.
