Hey fellow Final Fantasy VII strategist! When it comes to materia management, I recommend focusing on mastering a few key materias like Restore, Elemental, and Enemy Skill. This will give your party versatility in both offense and defense. For mission walkthroughs, don’t forget to steal from tough enemies for rare items and always explore every corner of the map for hidden treasures. In terms of character development, make sure to diversify your party members’ roles by leveling up different types of materia on each of them. This way, you’ll be prepared for any situation the game throws at you! Good luck on your adventures in FFVII!
