By and large, the artwork on individual cards in Dominion is nothing short of incredible. Some cards are better than others, but some of that is due to the card itself and what type of scene it can inspire the artist to complete. So as I was playing with the randomizer cards last night, I tried to decide what artwork I liked best. For me, there are no bad sets as a whole, but Hinterlands is my favorite. I really like the vibrant greens and blues used on some of the cards like Highway, Farmland, and Oasis.
Oddly enough though, my least favorite card (based on artwork) is from this set, in Mandarin.
I have no idea what's going on with his head and the odd contours/bumps, plus the background plants are just an outline...
So which expansions do you like, and why? Is it purely the artistic touch of individual cards? The unified theme of the entire expansion? I certainly play this game a ton online but the artwork itself will always provide a good reason to pull out the cards for an IRL game.
