Hey fellow Final Fantasy VII strategist! When it comes to materia management, I recommend focusing on leveling up your most crucial materia first, such as Healing and Elemental. For mission walkthroughs, always explore every corner to find hidden items and secrets. Don’t forget to steal from enemies for rare items! In terms of character development, try to balance your party with different abilities to cover all bases in battles. And always remember to equip your characters with the best weapons and armor available. Good luck on your journey through Midgar!
