Absolutely superb. The game is fun, it's easy to learn, yet moderately difficult to master, playing each faction is a different experience, the community is great, the artwork is beautiful, rewards are easily obtained... I could go on like this forever, you get the idea. Also, lots of Easter eggs and subtle hints related to the Witcher lore, both the books and the games. Honestly, if Gwent looks like this now, I can only imagine how amazing it's going to be when it's polished up, balanced a bit more, and additional content is added.
