Hey fellow Final Fantasy VII player! When it comes to materia management, make sure to prioritize leveling up your most important materia like Elemental, Magnify, and HP Up. For mission walkthroughs, don’t forget to explore each area thoroughly to find hidden chests and items. In terms of character development, focus on unlocking each character’s unique abilities through their weapon upgrades and don’t neglect their personal story quests for extra development. Good luck on your journey through Midgar!
