Hey fellow Final Fantasy VII fans! When it comes to materia management, I suggest prioritizing leveling up your magic and summon materias to unlock powerful spells like Ultima and Knights of the Round. For mission walkthroughs, always make sure to explore every corner of the map to find hidden treasures and don’t forget to steal from bosses for rare items. When it comes to character development, focus on each character’s unique strengths and customize their materia setups to complement their abilities. Feel free to ask if you need more specific tips for any part of the game!
