Anything from Leader Games and illustrated by Kyle Ferrin (Root, Oath, Fort…) feels like cheating but still, I absolutely adore their art style
Everdell, Photosynthesis, Parks, look nice as well
I also bought an updated edition of Costa Tuna just because of the illustrations: https://www.pamwishbow.com/client-work/project-four-yjynj-pafyx
I really like Spirit Island. It’s a grest game and the art style really adds to it as well. It really adds to my imagination not only to read the cards powers but to see the detail in the tiny art box on every card.
