Kobayashi's game playing was limited, noting her shock at seeing how advanced the
Famicom game
Final Fantasy III appeared. Development of
Romancing SaGa had Kobayashi create concept art for characters before the in-game character designs were made, due to the game having stories and concepts for its characters created in advance. She was given only a profile for each character that was about two paragraphs in length and told to use her imagination. This method of illustration differs from her work illustrating concepts for characters in novels, where she reads the text of the novel first. Kobayashi described this method as "half-terrifying and half-exhilarating." Kobayashi has done work to promote the
SaGa series, such as during an event celebrating the series' 25th anniversary in the
Saga Prefecture where her designs were on display in an art gallery. These designs were featured on porcelain plates (a process called "
Arita-yaki") among other things, which were either used as presentation for the event or sold. Multiple artbooks of her art have been published, including both for the
SaGa series, and for her own personal art. ==Artistic style and philosophy==
