Kingdom Hearts I, Kingdom Hearts II, Kingdom Hearts Chain of Memories and Re: Chain of Memories, Kingdom Hearts 358/2 Days and Birth by Sleep... Now the long awaited Kingdom Hearts Re:Coded is out in America for the Nintendo DS.
Kingdom Hearts Re:Coded is set after the original KH adventures. Jimminy Cricket kept a journal on both adventures, and the journal from the first is completely blank save for two messages. Jimminy decides it best to digitize the journal to decipher the strange messages. However, a virus threatens the Datascape, so King Mickey creates a digital Sora within the game. You'll have to play the game to figure the rest out on your own :)
