inal Fantasy X is a console role-playing game developed and published by Square (now Square Enix) as the tenth installment in the Final Fantasy series. It was released in 2001 for Sony's PlayStation 2. The game marks the Final Fantasy series' transition from entirely pre-rendered backdrops to fully three-dimensional areas, and is also the first in the series to feature voice actors. Final Fantasy X replaces the Active Time Battle (ATB) system with a new Conditional Turn-Based Battle (CTB) system, and uses a new leveling system called the "Sphere Grid".
