"XL Mature" is not a standard rating but a descriptive term, with "XL" usually denoting premium large-format cinema screens and "Mature" signaling adult-oriented content (17+ or 18+). These, or similar, packages in streaming services often include restricted, explicit, or intense material managed through parental controls.
Couldn’t play GTA 5, because of missing .DLL file. Now, everything works fine. Good service.
