Final Fantasy X Fainaru Fantajī Ten (ファイナルファンタジーX) is a role-playing video game developed and published by Square Enix. It is the tenth installment in the Final Fantasy series and the first game of the series to be released on the Sony PlayStation 2. Introduced in 2001, it was once among the top twenty best-selling video games of all time, and has sold more than 7.93 million copies worldwide. Set in the fantasy world of Spira, the game's story centers around a group of adventurers and their quest to defeat a rampaging force known as "Sin".

The game marks the Final Fantasy series' transition from entirely pre-rendered backdrops to fully three-dimensional areas, achieved with the PlayStation 2’s 294 MHz Emotion Engine processor. Though pre-rendered backgrounds are not entirely absent, their use has been restricted to less vibrant locations, such as building interiors. Final Fantasy X is the first in the series to feature a wide range of realistic facial expressions, as well as other technological developments in graphical effects achieved, such as variance in lighting and shadow from one section of a character's clothing to the next. Final Fantasy X is also the first in the series to feature voice-over actors, as well as the first to spawn a direct sequel, Final Fantasy X-2. (more...)
