Thronebreaker: The Witcher Tales comes to mind. It's essentially the single player aspect of Gwent. It's a prequel to the first game and is played in an isometric perspective with a full set of choices and consequences and is fully voice acted. CD Projekt didn't spare any expense on this game. The big difference though is that your army is made up of a customizable deck of cards, and so when you go into combat, it basically plays out like Gwent with several differences.
It's a great game that I was not expecting to have a deep story to! But it kind of came and went. I never really hear anyone ever talk about.
