Hey fellow Final Fantasy VII strategist! When it comes to materia management, make sure to prioritize leveling up your most important materia like Restore (for healing) and Elemental (for elemental defense). For mission walkthroughs, always remember to steal from bosses for rare items and use enemy skills like Big Guard for buffs. In terms of character development, focus on distributing your stat-boosting sources wisely to enhance each character’s unique strengths. Happy strategizing!
