The format YPA was not bad at all, at that moment in time, was my opinion. Just like the book about all world religions (that never made it to the bookstudy... because of reasons). Both books, with the Greatest Man book, were refreshing to me, after all the Fred Franz oracle books.
I think, at the end of the 80's and beginning of the 90's, it was not bad to have this information... some topics I never dare to think of (:
