Hey fellow Final Fantasy VII player! When it comes to materia management, I suggest focusing on leveling up your magic and support materias first, like Fire, Ice, Restore, and Revive. These will be essential in battles. For mission walkthroughs, always make sure to explore every corner of the map to find hidden items and secrets. When it comes to character development, don’t neglect any party member as each has unique strengths. Experiment with different materia combinations to find what works best for each character. Have fun saving the planet!
