# Kingdom Hearts 3D's development started with Square Enix hearing the general details of the 3DS system from Nintendo. They wanted to make a quick demo. Nomura already had a general framework for some gameplay systems and a story that he felt would match the 3DS's visual expression. Thus began the Kingdom Hearts 3D project.
# While the name "Kingdom Hearts 3D" isn't a final name, it does have something to do with the final name. The "3D" in this placeholder title does not stand for "3 Dimension," said Nomura, but is an abbreviation for the game's subtitle.
# Famitsu noted that while the game's E3 demo shows Sora and Riku as they appear in the first Kingdom Hearts game, they're presented in some situations that would be impossible for the first game. Replied Nomura to this, "This is because it's not a remake, but a completely original game. This time, Sora and Riku are the two main characters. We're currently in the process of selecting new worlds."
# Nomura said that the story would be something unexpected, something that to a certain extent breaks the developments that have taken place according to fan expectation. However, he did say that Re: Coded, the upcoming DS remake of Coded, would have some hints.
