Hey fellow Final Fantasy VII fan! When it comes to materia management, I recommend focusing on leveling up your most used materia like Elemental, All, and Restore. Don’t forget to link your materia for added effects! For mission walkthroughs, always explore every corner to find hidden items and secrets. When it comes to character development, consider each character’s strengths and weaknesses to build a balanced team. Experiment with different materia combinations to find what works best for your playstyle. Good luck on your journey through Midgar!
