Final Fantasy X

Final Fantasy X was one of the most popular FF games: it debuted the series roles on the PS2, and offered a very unique gaming experience, backed up by the most realistic graphics the series had ever seen. The very original story made the players want to continue, and the Sphere Grid made leveling up entertaining, a must in a game of such caliber.
