Yes, Aquelarre is a cool game. It got a kind of legendary cult aura in Europe for many years, I actually have the first edition in Spanish in black and white, it had a very graphic, stylized type of illustrations. The more recent editions are gorgeous, too. As a book, it never minced its words, LOL, in a very spanish way! They had some problems with conservative traditionalist media accusing them of Satan-worshipping, though not as bad as they would have had in the US, of course (I think).
You can see some of the black and white illustrations here:
