dude, I LOVE When I Dream! Also the idea of putting the draw pile inside a bedframe and covering the unused top of the cards with a pillow is so genius and creative!
Dixit sure had to be mentioned - when art is effectively your game mechanic it needs to be good. Though it depends on the card set, not a fan of the Dixit Odysey base set
I also played Mysterium which was made by the same people behind Dixit(I just checked and not at all, it's just the same mechanics with beautiful illustrations open to interpretation, my bad), and the game is a lot more engaging to me, but Dixit is one of the classics for french players!
