1-Jikan de Wakaru Kabushiki Toushi

Part of the budget-friendly "Simple 1500" series in Japan, 1-Jikan de Wakaru Kabushiki Toushi (roughly translated to Understanding Stock Investment in One Hour) is a fascinating outlier in the PlayStation library. Released in 2001, it isn't a game in the traditional sense but rather an interactive educational tool designed to demystify the stock market for the general public. Developed by Game Stage, it uses the PSX's hardware to present a "digital textbook" experience, guiding users through the basics of shares, market trends, and investment strategies through a series of menus, charts, and narrated lessons. It serves as a time capsule of the Japanese financial landscape at the turn of the millennium, packaged as a utility software for a console that, by then, was already transitioning into its legacy years.
