Hey fellow Final Fantasy VII strategist! When it comes to materia management, make sure to prioritize leveling up your most important materia like Elemental, All, and HP Up. For mission walkthroughs, always be prepared with plenty of Potions, Phoenix Downs, and status-healing items. Don’t forget to steal from enemies to get rare items! For character development, focus on each character’s unique strengths – like magic for Aerith, physical attacks for Cloud, and long-range for Barret. And always remember to experiment with different materia combinations to find what works best for your playstyle! Good luck out there in Midgar!
