Yup. I also got it just two days ago. I read the german manual. There are no technical differences in rules, just something you must have noticed yourself:
- Different set of tiles. Two tiles from inns&cathedrals.
- There are gardens but no abbot to put on them, they are purely decorative in this game.
I guess that means that you could bring abbot from "regular" edition, home brewing an expansion for C für zwei.
