Hey fellow Final Fantasy VII strategist! When it comes to materia management, I recommend focusing on leveling up your magic and support materias like Fire, Ice, Restore, and Barrier. These can be crucial in battles and boss fights. Make sure to link the right materias together for combo effects.

For mission walkthroughs, always explore every corner of the map to find hidden items and secrets. And don’t forget to steal from enemies for rare items! When it comes to character development, prioritize leveling up each character’s unique abilities to make them more versatile in battles. And don’t neglect their weapon upgrades for added bonuses. Happy strategizing!
