Hey there, fellow Final Fantasy VII fan! When it comes to materia management, I suggest focusing on leveling up your most crucial materia first, like healing and elemental spells. Don’t forget to link them strategically for added effects! For mission walkthroughs, remember to explore every corner for hidden items and shortcuts. Developing your characters evenly is key – don’t neglect any of them as each has unique strengths to offer in battles. Happy gaming!
