Well, I waited two years, but finally bought this game in a BOGO. It is terrific. The series has really improved from its earliest efforts, which were simple HO-heavy trivia. There still are lots of HO scenes in Mithridates, but the artwork is far superior and there are more puzzles and mini-games, some of which are challenging, indeed. For those who like Collectibles, there are two kinds of those as well. Also a plus is the globe-trotting nature of the locales involved. Some are places I have been and it is fun revisiting. In short, I am loving the game and definitely will replay it.
