Hey fellow Final Fantasy X explorer! When it comes to sphere grid progression, I recommend focusing on each character’s strengths. For example, Tidus is great for agility and speed, so prioritize those nodes for him.

For side quests, don’t miss out on the Celestial Weapons and the Monster Arena challenges for some epic battles and rewards. Make sure to visit Remiem Temple for the Chocobo Racing and Aeons’ battles too!

In terms of character builds, experiment with mixing different paths on the sphere grid to create unique combinations. Don’t be afraid to try out different strategies to find what works best for your playstyle. Happy exploring!
