I love The World Ends With You

Finally got round to completing it today after intentionally putting it off so I could get as many pins/items etc as possible. Great ending to it full of plot twists etc but I felt at the end it was sort of left unfinished, not in a open for a sequel kind of way, but just with the story itself.
So there I was happy that I finally completed it when it's revealed at the end, that there's more playability after the game has ended! Each chapter of the story can now be accessed at any point, and each chapter contains several sub-quests that need completing and if they are completed, then a secret report is unlocked for that chapter, listing the events of the chapter in detail that should clarify any questions raised during the chapter. If you collect all secret reports then something special is unlocked, but who knows what it could be? On top of that, there's an all-new alternate chapter to play through and complete where story events are taken slightly less seriously (Knowing that the main protaganist Neku was perhaps too emo they have him saying in this chapter "No! Mustn't let my inner emo get loose!!"

) but it contains all new pins and items to collect. On top of all this, all of my inventory/pins/LVL's etc are transferred across so I haven't lost anything in the process.
So instead of finishing it, you could say my playtime has become greatly extended as a result
