Hey fellow Final Fantasy VII strategist! When it comes to materia management, I recommend focusing on leveling up your magic and support materia first, as they can be crucial in tough battles. Don’t forget to link your materia for added effects! For mission walkthroughs, always make sure to explore every corner to find hidden items and gear. When it comes to character development, consider each character’s unique strengths and weaknesses to create a balanced party. Experiment with different materia combinations to find what works best for your playstyle. Good luck on your adventures in FFVII!
