Hyperdimension Neptunia

Setting

Games within the series takes place in the world of Gamindustri (ゲイムギョウ界, Geimugyō-kai, a pun on ゲーム業界 Gēmu gyōkai, "game industry"), which is divided into four regions/nations which are each ruled by one CPU: Planeptune, Lastation, Lowee, and Leanbox. Each region is completely different from the others in appearance and atmosphere, with each representing a specific video game console. Lastation represents the PlayStation, Lowee represents the Wii, and Leanbox represents the Xbox, while Planeptune represents the cancelled Sega Neptune. In the beginning of the story, the four goddesses are fighting each other for "shares" in a war known as the Console War. Shares are the manifestation of the belief citizens put into their goddess, and without shares a goddess dies. Because some of the games feature time and/or dimension travel there are slight differences in the settings for each title.

Development

Prior to Q3 2009, Compile Heart was conceptualising a new RPG project centred upon character designs by Tsunako, with the intention of collaborating with a partner company. This game was originally planned to feature three princess sisters and a protagonist. However, the partnership deal fell out, and as a result the project plans were redesigned and eventually became "Neptunia" close to the end of 2009 following the completion of Trinity Universe's development. During the early stages of the project, the characters Noire and Blanc were originally coloured red and blue respectively, however their colour schemes were changed to black and white so that they could better fit in with the new game setting and plot.

The release of the first sequel to the original game, Hyperdimension Neptunia mk2, saw the introduction of a reworked game engine and the replacement of various components such as the battle system and dungeons, which were completely rebuilt from scratch. Hyperdimension Neptunia Victory later built on this, with the parts from mk2 which were considered "weak" by the developers removed and improved, eventually setting Victory as the foundation for the design of future titles within the series. Following Compile Heart's collaboration with David Production to produce the Neptunia television animation series, the developers were able to change their approach to direction and script-writing based on their experience with the anime development staff, which resulted in the changes to the narrative found in the Re;Birth games on PlayStation Vita.

Release history

Hyperdimension Neptunia is the first game within the series, with the name originally derived from the scrapped Sega Neptune which combined the Sega Mega Drive/Genesis and Sega 32X into one unit, originally scheduled for release in 1994 or 1995 before the project was dropped after the release of the Sega Saturn.
