Gust Co. Ltd. was founded in 1993 in Nagano, Japan, as the first game software house in Nagano Prefecture. The company began by creating dôjinshi games for personal computers. Its first project was Story of King Ares (アレス王の物語) for the NEC personal computer. In 1994 the company became an official developer for the SonyPlayStation video game console, and its first PlayStation product was the simulation game Falkata (ファルカタ). In 1997, Gust released Atelier Marie, the first game in the long-running, popular, and iconic Atelier series. Since then the company has released several successful games for various home and portable video game systems. On 7 December 2011 the financial news source Nikkei reported that Tecmo Koei had bought all shares of the company from the stakeholders for 2.2 billion yen with the intention to make social games of Gust's Atelier console role-playing game franchise.
It was announced on July 28, 2014 that Gust will be absorbed by its parent company Koei Tecmo on October 1, 2014, and will continue to develop existing game series and new intellectual properties as "Gust Nagano Development Group".
In 2015, Gust released a new site called "Gust Social" exclusively for its social games, starting with Nights of Azure, Atelier Sophie and Ciel Nosurge as the first advertised, for the purpose of improving communication with fan feedback. The website allows for fans to make a Gust ID account which allows them to participate in surveys, buy products from the Gust online store, and a variety of other related content. Additionally, the Gust Social serves as an active news site for its new social games.
Games developed by Gust are known for their alchemy and item-crafting systems, distinctive character designs, and traditional or "old-school" graphical and storytelling style. In Japan, Gust has published its own games or cooperated with Banpresto. In North America, these games are published by NIS America. After the acquisition by Koei Tecmo, all games are published by them.
