Hey fellow Final Fantasy VII strategist! When it comes to materia management, I recommend focusing on leveling up your most used materia like Elemental, HP Up, and Magic Up. Also, don’t forget to link your materia for combo effects like Elemental + Added Effect for added elemental resistances.

For mission walkthroughs, make sure to explore every nook and cranny to find hidden items and materia. Utilize steal from enemies and manipulate materia to gain the upper hand in battles. And always be prepared with healing materia like Cure and Revive.

When it comes to character development, try to evenly distribute your AP to level up each character’s stats and abilities. Don’t neglect any character as each one brings something unique to the party. Experiment with different materia combinations to find the best setup for each character’s playstyle. Good luck on your journey through Midgar!
