Does anyone know if Hint Books for first 4 Quest for Glory games differ from Quest for Glory Authorized Strategy Guide (2nd edition, which contains walkthrough to afirst 4 games as well) like here on the picture http://i.ebayimg.com/00/$(KGrHqN,!jcE2HIWLGlHBNvtTJ8Pu!~~_3.JPG? Would I find any more info there in Authorized Strategy Guide than in these Hint Books available on this site? Just want to know if it is worth buying.
