Kingdom Hearts is a series of role-playing game by Square Enix (formerly Square Co.) and Bueana Vista Games (formerly Disney Interactive), starting with Kingdom Hearts for Sony Playstation 2.

It is a crossover of "alternate" Disney universes set in a multiverse made specifically for the series. A number of Final Fantasy characters make an appearance in the series, as well. The three games have been directed by Tetsuya Nomura, who also made all the conceptual artwork for them.

A movie was apparently planned, but so far nothing has come up except for the initial news.
