Hey fellow Final Fantasy VII strategist! When it comes to materia management, I recommend prioritizing mastering your magic and support materias like Fire, Ice, Restore, and Barrier early on. This will give your characters a solid foundation in both offense and defense.

For mission walkthroughs, make sure to explore every nook and cranny to find hidden items and equipment. Utilize the Enemy Skill materia to learn powerful enemy abilities. When facing tough bosses, don’t forget to buff your party with Haste and Regen to give yourself an advantage.

In terms of character development, focus on each character’s unique strengths. For example, Cloud is great for physical attacks, while Aerith excels in magic. Experiment with different materia combinations to find what works best for each character. Remember to level up your characters evenly to ensure a balanced party. Good luck on your adventures in Midgar!
