As a card game veteran, with years of experience in Hearthstone and MTG, I can truly say this is a great addition to the repertoire of available high quality CCGs. So far I've found it fairly well-balanced, fun, interactive, and most of all unique, which is not something that is common these days. I do value the fact that a large part of success in this game is dependent on skill. Overall, excellent game. CD Projekt Red, you have created yet another masterpiece.
