I don't usually buy a card game. I'm not a card game player. And I don't really want to play gwent (before and after playing this one). But I really like stories, and rpg. The story here, is really well written Choice have consequences, and we really feels it. The card game here support the narrative experience, we have the impression of controlling an army without playing a long RTS. I play in hard mode, and the game is still accessible (but hard, it's smart hard). My only concern is when you find a good deck, you don't really need to adapt that much. And game can be a bit repetitive. And we cannot save deck, so I don't want to make too many change. tl:dr: Great stories with impactful choice, smart game, can be repetitive at the end.
