FFX: Tidus
Tidus is a young Blitzball star who finds himself transported to Spira after his home city of Zanarkand is destroyed by Sin. In Final Fantasy X, Tidus typically follows a path on the Sphere Grid that emphasizes fast, physical attacking. The Sphere Grid system allows players to customize character development, but characters often gravitate towards intended roles, such as Tidus's natural inclination for offensive capabilities.
The Sphere Grid is a core leveling system where earning AP grants Sphere Levels (SLVLs). These SLVLs are used as currency to move across the grid: 1 SLVL for untraveled paths (one node at a time) or four nodes on traveled paths. Players use Spheres to place or activate nodes, gaining stat boosts or new abilities. While the original Sphere Grid guided characters into specialized roles, the Expert Sphere Grid, available in the HD Remaster (and PAL/International PS2 versions), offers more freedom, allowing for diverse character builds.
