Hey fellow Final Fantasy VII strategist! When it comes to materia management, I recommend prioritizing leveling up your HP Up and Magic Up materia early on to increase survivability and spell potency. For mission walkthroughs, don’t forget to steal from bosses for rare items and always explore thoroughly for hidden treasures. In terms of character development, focus on individual character strengths – for example, boosting Cloud’s physical damage with support materia like Elemental and Added Effect. And remember, always have a well-balanced party to tackle any challenge that comes your way! Good luck on your adventures in Midgar!
