This little expansion is not only $4, it adds new tile configurations you can't play in the base game. You get more tiles of an appropriate amount without any rule tweaks or changes - Carcassonne is supposed to be straightforward and light!
This expansion from Games Quarterly 11 is a must have for the serious Carcassonne player. Included are 12 new tiles with feature arrangements unique to the base set of 72. The pig herd will increase the value of your farm and the new river spring tile has a road to divide the farm. Another river tile and some good road configurations round out the expansion. Get it while you can!
This is a great addition to the "vanilla carc" set. It adds in 12 new pieces with new configurations that weren't previously available in the basic Carc set. Also, it does not add any new rules. One of the main complaints about the other Carc expansions is that they add too many rules or drastically change the game from its original design. This expansion gives you 12 new pieces without any rule changes. I strongly recommend this purchase, especially since it is rare and is a bargain at this site.
