Hey fellow Final Fantasy VII strategist! When it comes to materia management, I suggest focusing on leveling up your Magic and Summon materias for powerful spells in battles. Don’t forget to link Support materias like HP Up or MP Up with your main materias for added benefits. For mission walkthroughs, remember to explore every corner to find hidden items and secrets. When developing your characters, consider their unique strengths and weaknesses to optimize their roles in the party. Keep grinding and experimenting with different materia combinations for the best results! Good luck on your adventures in Midgar!
