Persona 2 was split into two games, Innocent Sin and Eternal Punishment. However, America and Europe only got Eternal Punishment. There are some theories as to why Innocent Sin was not released over seas, but the real reason is unknown and the updated PSP remake of both games did make it to America and Europe.
