According to the information under "Specifications", the more expensive version for Fr. 26 is in French and Italian, whereas the one for Fr. 25 is in German and English. I did not notice any other difference.

The purchase is worthwhile, 1. -not the most important but also good, you can keep all the expansion and the main game in this box,
2) -new colour purple / new special cards
3. there are new additional rule cards that you can add to the game, which adapt existing rules or new rules themselves (is great):D

So I can only recommend it, hope this helped a little.
