I'm not getting tired of mentioning that I ran to the store and bought the 1st edition when I heard the changes in the revised edition :)Okay, I could live without the Coffin-Box... But I like the 3D mountains (and I don't know how to create my own like Tonman^^) and most of all: the punchboard faction sheets are replaced with those paperquality sheets from Civilization. I'm very happy with my fist edition even though it has some misprints on the cards and still the old rulings.
However you can just download the revised rules and use them with the old version.
