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 Ruana just because of the illustrations: https://www.pamwishbow.com/client-work/project-four-yjynj-pafyx
Maybe I’m just a bird man but Wingspan is absolutely stunning. I bought second copies of the base game and addons to put cards into a binder
I was hopping in to comment wingspan and then immediately realized of course everyone had already been talking about how beautiful this game is
