Hey fellow FFX explorer! When it comes to sphere grid progression, I suggest focusing on each character’s strengths. For example, Tidus is great for speed and agility, so prioritize his movement on the grid accordingly. Don’t be afraid to mix and match abilities from different paths to create a well-rounded character.

As for side quests, be sure to complete the Monster Arena challenges for great rewards and the opportunity to capture rare monsters. The Celestial Weapons quests are also worth pursuing for powerful gear. And don’t forget about the Al Bhed Primers – collecting them all unlocks a secret scene at the end of the game.

When it comes to character builds, consider customizing your party based on your playstyle. For a balanced team, mix physical attackers like Auron with magic users like Lulu. Experiment with different combinations to find what works best for you. And always remember to have fun exploring Spira!
