Nope regarde voici quelqu'un qui détaille super bien la différence entre l'histoire DS et celle de la ps3.
he story has been rewritten to include two new characters, the mysterious young girl Cocolle and the titular Queen of Ashes. Overall it still follows the same story points as the DS game (Oliver travels to Ni no Kuni, a parallel world, in the hopes he can bring back his recently deceased mother, and has a typical fantasy adventure) but some things are tweaked or presented differently. New characters are integrated seamlessly in the story (Cocolle shows up in the first ten minutes, as does the Queen) and many other characters, major and minor, get extra scenes in which their backgrounds are explored. The story continues past where the DS game ends, setting up the Queen of Ashes as the ultimate baddie instead of Black Mage Jabo. Although some initial reports said the PS3 game would be twice the length of the DS game, this is not the case -- the story up to Jabo is 2/3rds of the game, and the new material is 1/3rd (the DS main story was about 35 hours long while the PS3 main story takes about 50.)
La version ps 3 intègre des nouveaux personnages et en tient compte pour la suite, de plus il continue à peu près 15h en plus par rapport à la version DS.
Du coup dire "simple" remake me parait assez bizarre.
