Xenosaga: Pied Piper
Xenosaga: Pied Piper is a role-playing video game co-developed by Monolith Soft, Namco Mobile, and Tom Create. The game was published by Namco in 2004 for mobile devices. A spin-off of the "Xenosaga" trilogy and forming part of the "Xeno" metaseries, the storyline follows the human life of cyborg Ziggurat 8—a key character in the "Xenosaga" trilogy—a century before the events of "Xenosaga Episode I". Gameplay follows a similar system to the mainline "Xenosaga" games but adjusted for mobile devices.
Monolith Soft
In 1999, Takahashi talked with Hirohide Sugiura, who had likewise worked at Square and was beginning to feel frustrated due to a lack of creative freedom. After discussing the matter, the two decided to create their own company and pursue projects they wanted to create. When planning their new company, Takahashi and Sugiura decided that they needed a publisher with substantial market presence to help them rather than being an independent studio. Takahashi and Sugiura approached multiple companies for support, but most of the companies they contacted outright rejected their offer as they believed that Monolith Soft should be an independent company. However, Namco were interested in investing into Monolith Soft as a dedicated subsidiary, whilst handling logistics and marketing so that the core staff could focus on game development. An important supporter of Monolith Soft was Namco's founder Masaya Nakamura, who shared many of Takahashi and Sugiura's goals and ideals. Monolith Soft is noted as being one of a group of video game companies—alongside Sacnoth, Love-de-Lic and Mistwalker—founded by Square staff who had worked on notable games produced during the 1990s. The company was officially founded on 1 October 1999 by Takahashi, Sugiura, and Yasuyuki Honne, who had worked at Square on both the "Chrono" series and with Takahashi on "Xenogears". The company's offices were originally based in Yokohama.
Monolith Soft
Monolith Soft's first project was "Xenosaga Episode I", a role-playing game (RPG) for the PlayStation 2. "Xenosaga" was a spiritual successor to "Xenogears"; development began in 2000 when enough staff had been gathered, lasting approximately two years. As with "Xenogears", the game was scripted by Takahashi and Tanaka, who planned out the "Xenosaga" series as a hexalogy. In 2001, Namco producer Shinji Noguchi and Monolith Soft's Tadashi Nomura conceived a new IP for the GameCube unconnected to "Xenosaga". Titled "", development began six months after the concept was formed, with Honne acting as director. The game development staff of the company was now divided between the "Xenosaga" series and "Baten Kaitos", the latter a project driven by the younger developers at Monolith Soft. "Baten Kaitos" was co-developed with tri-Crescendo, which came about due to both submitting designs to Namco, which suggested they work together on the project. In 2003, Honne was approached by then-CEO of Nintendo Satoru Iwata about developing a new entry in the "Mother" series for GameCube. Honne created a pitch themed around a "felt-style recreation of 80s America", but the idea was firmly rejected by series creator Shigesato Itoi.
