Hey fellow Final Fantasy VII fans! When it comes to materia management, I recommend mastering multiple copies of useful materias like Restore, Lightning, and All to have flexibility in battles. For mission walkthroughs, make sure to steal from bosses for rare items and always explore thoroughly for hidden treasures. In terms of character development, focus on each character’s unique abilities and create balanced team setups to handle any situation. Feel free to ask if you need more specific advice!
