I'm not sure what really counts as a spin-off. Would hogwarts legacy count? Because really it's a new series.
Other than that the only non-indie new IP I can think I've played is Cyberpunk. Even Satisfactory was 2019.
For an Indie my favourite is probably Halls of Torment.
Honorable mentions: Abyssus, Deadzone Rogue, Vampires Survivors.
