Hey fellow Final Fantasy VII strategist! When it comes to materia management, I recommend focusing on leveling up your most used materia first to enhance your characters’ abilities. Don’t forget to link compatible materia for added effects in battles. For mission walkthroughs, make sure to explore each area thoroughly to find hidden items and secrets. When it comes to character development, consider each character’s strengths and weaknesses to optimize their materia setup and roles in battle. Remember to level up your characters evenly to keep them balanced and ready for any challenge! Good luck on your journey through FFVII!
