the PS3 Eternal Sonata features a raftload of enhancements, ranging from the trivial to the extremely impressive. Nearly everything related to the game's story and characters is getting an upgrade. In addition to two new playable characters (Prince Crescendo of the Baroque kingdom and his fiance Serenade, both of whom appeared in the 360 version but weren't controllable), there are a handful of new dungeons to explore and a variety of new quests, including one that brings you into the forest the agogo sprites call home and another that more fully explores the story behind Polka's illness. The game now has multiple endings that branch out depending on your decisions in-game, and you can also dress up your party in new costumes, which you'll find in treasure chests along the way. Even the audiovisuals are getting a little boost -- there are new 2D illustrations for all the main characters, and a selection of new music is set to be added from composer Motoi Sakuraba and Russian pianist Stanislav Bunin.
In addition to everything that was said above; it's important to note that a number of major story changes have been made in the PS3 version. There are many additional scenes and changes to dialogue, including some important changes to the opening and ending of the game.
