Character advancement is one of the defining aspects of any role-playing game, and Final Fantasy X uses an interesting system for it that's rather different from that of most such games. Instead of gaining experience levels as you win battles, you gain points that you then use on what's called the sphere grid. The sphere grid is like a large board-game map, though it looks more like a maze. At almost every step of the grid, you'll find points that raise attributes such as strength, hit points, magic power, agility, and more and other points that teach new spells and new special abilities. Characters start out at different points on the grid, and the surrounding area on the grid will roughly correspond to their inherent talents.
