Hey, fellow Final Fantasy VII strategist! When it comes to materia management, I recommend focusing on leveling up your most important materia like Elemental, HP Up, and Magic Up. Always have a good balance of offensive and defensive materia equipped to handle any situation.

For mission walkthroughs, don’t forget to explore every corner of the map to find hidden items and secrets. Take your time to level up your characters before tackling tougher missions to make things easier.

In terms of character development, prioritize unlocking each character’s limit breaks and experimenting with different party combinations to find what works best for you. And don’t forget to customize your characters with the right equipment and abilities to maximize their potential in battle. Good luck with your adventures in FFVII!
