Hey fellow Final Fantasy X explorer! When it comes to sphere grid progression, make sure to focus on your character’s strengths. For example, Tidus is great for agility and speed, so prioritize those nodes for him. Don’t be afraid to mix and match different paths on the grid to create unique character builds.

As for side quests, don’t miss out on the Monster Arena challenges for some great rewards and tough battles. Also, make sure to collect all the celestial weapons for your party members as they can be real game-changers in tough fights.

Lastly, experiment with different character builds to see what works best for your playstyle. Whether you prefer a tanky Auron, a magical Lulu, or a versatile Yuna, there are plenty of options to customize your party to suit your preferences. Happy exploring!
