Mysterium. Is. Beautiful.
I don't think I've seen a more beautiful game. The entire experience of opening the box, setting up the game, analyzing the cards... The design and artwork is absolutely top notch on every element of the game and this is what makes Mysterium stand out from other tabletop experiences. The game has you looking at each card in such detail, that I felt it was designed to show off the artist's talents.
Playing Mysterium is a very quiet, mellow experience and personally not my favorite. It feels like you're in a museum admiring beautiful works of art and discussing their meaning with some colleagues. That's fine. There's no problem with that. I can just usually scratch that itch about once a year or so and be just fine.
Come for the artwork. Soak it in and then play something else.
