Hey fellow Final Fantasy VII strategist! When it comes to materia management, I suggest focusing on leveling up your most used materia first, like Restore and Lightning. Make sure to link them strategically for combo effects. For mission walkthroughs, always explore every corner to find hidden items and secrets. Don’t rush through areas, take your time to level up your characters. When it comes to character development, try to balance your party with different abilities to cover all aspects of battles. Experiment with different combinations to find what works best for your playstyle. Good luck on your journey through Midgar!
