When playing Dragon Quest IX, players are faced with immense amounts of game information. In order to save hundreds of hours of learning and memorizing intricate game details, many players prefer to simply refer to a guide as they play. This thesis project aims to develop a guide app to fulfill this role. The app will provide players with an interactive and user-friendly platform to access detailed information on equipment, weapons, items, recipes, and monsters within the game. The project will involve extensive research and analysis of the game's data, as well as the development of a database to store and organize relevant information. Ultimately, the guide app will provide an invaluable resource for players looking to enhance their Dragon Quest IX experience and achieve a deeper understanding of the game's intricacies.
