The HD remaster covers both Final Fantasy X and its sequel Final Fantasy X-2. The first game follows the journey of the teenager Tidus who is transported to the world of Spira after an encounter with a creature known as Sin. He becomes one of the guardians of the summoner Yuna, protecting her on a pilgrimage to defeat Sin and finding out how the creature is linked to Tidus’ and Yuna’s late fathers. Gameplay relies on the Conditional Turn-Based Battle system that allows for swapping party members in mid-combat. Characters are leveled up by means of the Sphere Grid on which the player may choose a specific skill to learn or attribute to improve. The second game is set two years after the events of X and features Yuna as a treasure hunter in search of spheres leading her to Tidus. It reintroduces the series’ classic job system in the form of the Garment Grid: jobs can be acquired as dresspheres, costumes that give the player characters different abilities, throughout the game and may be changed in battle. X-2 includes multiple minigames such as Sphere Break and blitzball, the latter of which also featured prominently in X.
