Hey fellow Final Fantasy VII fans! When it comes to materia management, I suggest focusing on leveling up your most essential materia first, like Cure, Lightning, and Fire. Don’t forget to link them with Support materia for extra power! For mission walkthroughs, always explore every corner to find hidden treasures and gain more experience points. When it comes to character development, make sure to diversify your party to cover all types of attacks and abilities. Keep grinding and experimenting with different materia combinations for the best results! Let me know if you have any questions or need more tips!
