Hey fellow Final Fantasy VII strategist! When it comes to materia management, I recommend prioritizing leveling up your magic and summon materias for powerful spells in battles. Don’t forget to link support materias like HP Up or MP Absorb with your offensive materias for added benefits. For mission walkthroughs, always explore every corner of the map to find hidden items and secrets. When it comes to character development, focus on specific roles for each character to maximize their potential. For example, make Cloud a physical attacker with strong melee materias, while Aerith can be your primary magic user with healing and support materias. Happy strategizing!
