Hey fellow Final Fantasy VII strategist! When it comes to materia management, I recommend focusing on leveling up your most important materia first, like Lightning and Restore. For mission walkthroughs, make sure to explore every corner of the map to find hidden treasures and shortcuts. When it comes to character development, don’t neglect your weaker party members – everyone has their strengths, so rotate them in battles to level them up evenly. And always remember to customize your materia setups based on the enemies you’re facing in each mission! Happy gaming!
