Hey fellow Final Fantasy VII strategist! When it comes to materia management, I recommend focusing on leveling up your most essential materia like Restore, Lightning, and Enemy Skill. Don’t forget to link them strategically for combo effects. For mission walkthroughs, make sure to explore every corner for hidden items and don’t rush through battles – take your time to strategize. When it comes to character development, remember to allocate stat-boosting sources wisely and experiment with different party combinations to find the best synergy. Happy gaming!
