Hey fellow Final Fantasy VII strategist! When it comes to materia management, I recommend focusing on mastering key materia like HP Plus, MP Plus, and Enemy Skill early on. This will help your characters stay alive longer and have access to powerful spells. For mission walkthroughs, make sure to explore every corner of each area to find hidden items and secrets. When it comes to character development, try to balance your party with different roles like tank, DPS, and support to have a well-rounded team. Keep grinding and don’t forget to have fun!
