The „Big Box“ is so far the biggest edition of Carcassonne, that is available. It consists of:
Carcassonne base game
+ 5 Expansions
It is appropriate for beginners as well, because you can play with the base game alone in the beginning and add further expansions from time to time.
The more expansions you add, the longer the game goes on. Normally the base game alone takes about 30 minutes, regarding to the game package. It is appropriate for 2 to 6 players.
On the inside of the package there are luckily some instructions on how to sort all the expansions back into the huge package.
The following 5 expansions are included into the Big Box edition:
» Inns and cathedrals ( 1. Expansion )
» Traders and builders ( 2. Expansion )
» The princess and the dragon ( 3. Expansion )
» Abbey and mayor ( 5. Expansion )
» Bridges, castles & bazaars ( 8. Expansion )
I really recommend this edition to everyone. Even the customer reviews confirm that. Carcassonne is for so many people the best strategy board games since more than 10 years. There still will be new expansions and mini expansions developed for the games, and there is no end in sight.
