Hey fellow Final Fantasy VII strategist! When it comes to materia management, I recommend focusing on leveling up your magic and support materia first. Pairing elemental materias with your attacks can give you an edge in battles. As for mission walkthroughs, don’t forget to explore every nook and cranny for hidden items and secrets. When it comes to character development, make sure to allocate your AP wisely to level up your characters’ stats and unlock new abilities. And always remember to have a balanced team to handle any situation the game throws at you! Good luck on your adventures in Gaia!
