Hey there, fellow Final Fantasy VII strategist! When it comes to materia management, I recommend focusing on leveling up your magic and support materias like Fire, Ice, Restore, and Revive. This will give your characters a good balance of offensive and defensive abilities.

For mission walkthroughs, make sure to explore every nook and cranny to find hidden items and equipment. Also, don’t forget to steal from enemies during battles to get rare items that can help you along the way.

When it comes to character development, try to spread out the AP evenly among your party members so everyone can learn new abilities and level up their materia. Don’t neglect upgrading your weapons and armor as well to stay prepared for tough battles ahead. Stay strong, and may the power of materia be with you!
