Hey, fellow Final Fantasy VII strategist! When it comes to materia management, I recommend focusing on leveling up your key materia like All, Restore, and Elemental. These can be real game-changers in tough battles.

For mission walkthroughs, always make sure to explore every corner of a location to find hidden items and secrets. And don’t forget to steal from enemies – you never know what rare items you might get!

In terms of character development, try to balance out your party with a mix of physical attackers, magic users, and support characters. Experiment with different materia combinations to find what works best for each character’s playstyle. And always remember to have fun while saving the planet!
