Hey fellow Final Fantasy VII strategist! When it comes to materia management, I suggest focusing on leveling up your magic and support materias like All, Restore, and Elemental. These can be super handy in tough battles. For mission walkthroughs, make sure to explore every nook and cranny to find hidden items and secrets. When it comes to character development, try to balance out your party with different abilities to cover all your bases in battles. And don’t forget to experiment with different materia combinations to find the ones that work best for your playstyle! Good luck on your adventures in FFVII!
