DS:Style is a series of educational software products for the Nintendo DS console. The series was created and published in Japan exclusively by Square Enix, a Japanese video game developer and publisher, and developed by both Square Enix and several other companies. It includes reference guides, travel guides for different countries or cities, and study guides for Japanese professional licensing and civil servant exams. The first nine products in the series were announced on April 4, 2007 and the first five were released on July 5, 2007; the last DS:Style release was on February 3, 2011. Several of the products were named after other non-software products, such as the Lonely Planet series of travel guides. The releases, as they fell in the line between games and software products, went largely unreviewed. Critics' reactions to the series were tepid; they felt that the products would sell well, given the publisher and subject matter, but that there was little interesting about them. (Full list...)
