Please give me any major changes in mechanics, or cast. If there is a historical change that is significant i.e. the Germans won WWII, Riddle did become a teacher and took over Hogwarts, etc. Or themes, comic fun to a horror theme is just wrong, though there was that "Can the Scooby Gang survive a true Villain" campaign. With an understanding of the big things we should be able to have fun while "Exploring" the new world dynamic.
