It is much more than just Gwent's single player campaign. A 40 hour long RPG (battles played through Gwent) with a fantastic story, tough choices, colorful characters ant beatiful locations. The narrative feels like a very well voice acted audiobook, very much reminded me of the Witcher books. Anyone who enjoyed the Witcher games or books will love this (there is even an option to skip battles on the easiest difficulty, for the ones that don't like Gwent). Overall a fantastic game, definitely surpassed my expectations.
