Final Fantasy X-2's story is structured around 'Episodes' within each 'Chapter.' Your progress is tracked by a 'Completion Percentage' displayed on the main menu. This percentage is crucial for unlocking the best ending. To achieve 100% completion, you'll need to complete all main story missions, many side quests, and engage in specific conversations or actions. The game often presents choices that can influence the story path and completion percentage. Pay attention to dialogue options, as some choices can lead to different outcomes or unlock new missions. The 'Episode Complete!' notification signifies the successful conclusion of a major story segment in a particular region. Aiming for high completion on your first playthrough is recommended to experience the full narrative and unlock all secrets.
