Hey fellow Final Fantasy VII player! When it comes to materia management, I recommend focusing on leveling up your magic and support materias like Heal, Lightning, and Barrier. Spread out your materias among your party members to cover a wide range of abilities. For mission walkthroughs, make sure to explore every corner to find hidden items and secrets. When it comes to character development, prioritize upgrading your characters’ weapons and armor to enhance their stats. Don’t forget to complete side quests for extra rewards and experience points!
