Hey there! When it comes to materia management in Final Fantasy VII, I recommend focusing on leveling up your most essential materia first, such as Cure, Lightning, and Restore. Make sure to link your materia strategically to maximize their effects in battle. For mission walkthroughs, remember to explore every corner of the map for hidden items and secrets. When it comes to character development, consider each character’s unique strengths and weaknesses to build a well-balanced party. Don’t forget to experiment with different materia combinations to find the best setups for your playstyle!
