Originally released in the U.S. in 1991 as Final Fantasy II, the game originated the series’ Active Time Battle system that was used up until Final Fantasy XI. It was also the first game in the series to feature a character-driven plot. The game's star, Cecil, is a Dark Knight who begins to question his king’s motives and eventually becomes embroiled in an epic story that spans three realms and has twelve playable characters.
This new version will contain a plethora of new additions to the game including: new 3D graphics, new bits of story, cut scenes with voice-overs, a new score by series composer Nobuo Uematsu, and a whole lot more.
Just being nit-picky here, but FFX went back to turn-based battles.
