Hey fellow Final Fantasy VII strategist! When it comes to materia management, I recommend focusing on leveling up your magic and support materias like Cure, Lightning, and Barrier. These can be crucial in tough battles. For mission walkthroughs, always make sure to explore every corner to find hidden items and secrets. In terms of character development, don’t neglect any of your party members, as each has unique strengths that can be valuable in different situations. Keep grinding and experimenting with different materia combinations for the best results in battles!
