Hey fellow FFX explorer! When it comes to sphere grid progression, focus on unlocking key abilities for each character first before branching out. Make sure to use the “clear spheres” to backtrack and grab any missed nodes.

For side quests, don’t miss out on the Celestial Weapons and Aeons quests for some powerful rewards. Also, be sure to complete the Monster Arena challenges for great AP and item drops.

As for character builds, tailor each character to their strengths. For example, Tidus is great for agility and physical attacks, while Yuna excels in magic and summoning. Experiment with different paths on the sphere grid to find the best build for your playstyle. Happy exploring!
