Hey there, fellow Final Fantasy VII strategist! When it comes to materia management, make sure to prioritize leveling up your most important materia like Cure, Fire, and Lightning. Don’t forget to link them with Support materia to enhance their effects. For mission walkthroughs, always be prepared with healing items and status ailment cures. Utilize each character’s unique abilities to tackle different challenges. In terms of character development, focus on diversifying your party members’ roles to have a well-rounded team. Experiment with different materia combinations to find what works best for your playstyle. Happy gaming!
