earlier work. The music quality could be greatly increased due to the incorporation of a dedicated memory map. The character and demon designs were created by Kazuma Kaneko. Megami Tensei II was Kaneko's first work on the series, having played the first game and come to work at Atlus without knowing they were its developers. When creating the demon designs, Kaneko was inspired by the monsters featured in the Godzilla series, wanting to put his own design twist on creatures both from Japanese folklore and world mythology. For each design, he took their main mythical characteristics and the wide differences between creatures from different cultures, and incorporated them into the game. His demons' attitudes drew inspiration from North American mythology with their wish to feed on the negative emotions of humans. Commenting later, he felt his early designs were "forced", and said that Nintendo were concerned about the mature aspects of his demon designs to the point of asking him to remove the nipples from a naked female figure. While the original game was based on Nishitani's novels, for the second game Atlus decided to create an original story. The game's scenario, demon conversations and world design were written by Kazunari Suzuki, who had also worked on the original story elements for the first game. A second writer on the project was Ryutaro Ito. Work had already started on the project when he joined Atlus at the recommendation of Suzuki's father. Ito was responsible for much of the character dialogue, including the notably apathetic greetings of shop owners. The game's inclusion of multiple endings based on player choice for factions labelled "Law" and "Chaos" was intended to question the traditional ways the two sides were portrayed in mythology and popular culture: according to Okada, the aim was to make players question whether the forces of Law were an ideal faction and Chaos something to be abhorred. A controversial scene where the protagonist lost his arm was inspired by a scene in the second Star Wars movie The Empire Strikes Back. As a homage to the original novels by Nishitani, Ito included the name of the novels' protagonist during the closing segment of the game. Release Megami Tensei II was released for the Famicom by Namco on April 6, 1990, on a 4-megabit cartridge. The game was ported to mobiles; it released on September 1, 2006, for NTT DoCoMo models, and
