German edition. How language dependent is the game?
I own the "German" edition, and it has a two-sided board, one in English, one in German. They differ in terms of what part of the Europe and the Mediterranean they are centered on, but that's it. So you can play once on the English side, and for your next game, you'll understand the German side. The cards are fairly language independent, and the rules come in English as well as German.
My answer: mostly language independent, not very language dependent at all.
