this guide is helpful for finding all the extra hidden materia, weapons , & side missions.But it did lack something, for example it does NOT have all the enemy skills ( it's missing 3), whats up with the tissues, 1/35 Shinra attack soldiers, autographs, Dio's Diary etc.The bestiary could also use some work, for example the Master Tonberry CAN be morphed into a ribbon, Cactaur CAN be morhed into a tetra element, all the creatures on the Crashed Gelinka CAN be morphed into a source.Also in the bestiary the Gi Spector is shown twice.I know it may sound like there is alot wrong with the guide but there really isn't , it's a huge helpful guide & it assists you alot in this huge colorful & beautiful game.In other words if you are looking for a guide for this game this is it.
