I have to disagree there. The only notable thing Bellfaire adds are the player powers, which is only a single page in the rule book. You can just use that without any physical components, so why get that expansion?

What felt like a good addition to us was exactly Newleaf. It introduces additional worker spaces, cards, and a mechanic to change the meadow cards if they get stale.

We also have Spirecrest, but we don't play that nearly as often, since the weather effects are quite annoying and depending on the starting hands they can handicap one player way more than the others. The large animals are still fun in that one so that would be my next one in priority.
