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
Yeah it's Oath, I bought it, I don't even know if I'll be able to play it with friends, but I need all the Kyle Ferrin I can humanly collect in my life. His cute critters and goofy faces and lovely sketch lines and textures are just so adorable
