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
Oh yeah Jakub Różalski’s style is sooo good, there’s also a video game that pretty much has the same setting as Scythe on Steam, called Iron Harvest, I wouldn’t be surprised if he also worked on it!
