is there any recommended walkthrough or easy guides. I know most of the game I'm just not wanting to get to the end and discover I have missed a materia like last time I played through. I also know I have to do Yuffie's quest before the 2nd act finishes
If you want to collect all materias in the game then any guide in gamefaqs would serve your purpose, all guides regarding this are more or less the same so there shouldn't be any issue with which one you pick.
