The World Ends With You is one of those DS RPG titles that may not be well-known, but is critically acclaimed and loved by its fans. It's a gem of the DS library, which makes the recent tease of a sequel from Square Enix music to our ears.
As reported by Andriasang, Tetsuya Nomura — a key figure in The World Ends With You and the upcoming Kingdom Hearts 3D: Dream Drop Distance — described the relevance of providing voiced dialogue for Raimu in the 3DS title, a character from the cult DS release: it's apparently important "out of consideration of the future of The World Ends With You series."
When pressed on what this meant, Nomura was rather coy: "Regarding The World Ends With You, I can't say anything at present... (laughs). But there probably is something."
Of course that doesn't necessarily mean that any sequel will be on a Nintendo system, but hinting at a sequel to a DS title while discussing a 3DS game at least makes it a solid possibility. Have any of you played The World Ends With You, and are you interested in a sequel?
