This expansion adds a lot of really good additions to the excellent Fields of Arle. Most notably, it allows for a 3rd player to join the fun. It also adds some new actions, new buildings, and tea as a new resource. I recommend playing a good amount of the original before adding this. The base game has a LOT of options to explore already. I also think getting the two-player game down before adding a third helps. Once you add the expansion, you will always use it. Fields of Arle was already my favorite Rosenberg game. This makes it even better!
