Neptune is set in the video game business world where Neptune, the protagonist, has to thwart the Goddess Magicon. (note: Magicon are a term used for DS flash carts in Japan.) The twist is Neptune is a video game console, more specifically a moe personified video game console. Basically, you’re a console that can transform into a beautiful girl.
Other than the video game world setting, Neptune has all of the makings of a standard RPG – quests, dungeons, and leveling up.
Neptune is due in stores this summer in regular and limited edition packages. While the game has not been announced in North America, Compile Heart seems to be shopping for a publisher. At GDC, Neptune was on their behind closed doors product list.
