Hey fellow Final Fantasy VII fans! When it comes to materia management, I recommend focusing on mastering a few key materia like Magic, Command, and Support. This will allow you to customize your characters based on your playstyle. For mission walkthroughs, always make sure to explore every corner to find hidden items and secrets. When it comes to character development, remember to balance upgrading your stats with learning new abilities to have a well-rounded team. Keep grinding and experimenting with different strategies to conquer every mission!
