Hey fellow Final Fantasy VII strategist! When it comes to materia management, I recommend focusing on leveling up your most important materia like Elemental, Restore, and Magic Plus. Don’t forget to link them for added effects! For mission walkthroughs, always remember to explore every corner for hidden items and secrets. When it comes to character development, prioritize upgrading each character’s unique abilities and finding the best equipment for them. And don’t be afraid to experiment with different materia combinations to find what works best for your playstyle! Good luck on your adventures in FFVII!
