Hey there, fellow Final Fantasy VII strategist! When it comes to materia management, I recommend focusing on leveling up your magic and support materia first, as they can be real game-changers in battles. Make sure to pair complementary materia together for maximum effect, like pairing Elemental with a magic materia to add elemental properties to your attacks.

For mission walkthroughs, always pay attention to enemy weaknesses and adjust your materia accordingly. Don’t forget to explore each area thoroughly to find hidden items and shortcuts that can make your journey easier. And when it comes to character development, be strategic in allocating your AP to level up your characters’ stats and unlock their best abilities.

Remember, practice makes perfect, so don’t be afraid to experiment with different materia combinations and party setups to find what works best for your playstyle. Good luck on your adventures in Midgar!
