The extensions have to be careful that previous enlargements do not match the new version. Since you should then get the new extensions, the "Catan seafaring Edition" particularly like me. The new extension, although I have not tried, but the previous game I had often combined with it and found it exciting.
Catan is, next to risk my favorite game so you can play four before an evening, particularly with an expansion has the game the correct playing time.
The instructions are easy to understand, there is also an almanac, it finds then run some more detail. In the new game pad there is also a "Play It Smart" - app, by this one can bring the robber to life, but this app is not a must, you can make the game also remains without this app play.
A well-known game that is far from getting on in years, still modern and sexy!
