Romancing SaGa
Kobayashi's game playing was limited, noting her shock at seeing how advanced the Famicom game "Final Fantasy III" appeared. She was approached to work on the Japanese role-playing game "Romancing SaGa" by a representative from Square Co. (now Square Enix) following the release of a book for her illustration collection. 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. Sprite designer Kazuko Shibuya came to visit Kobayashi to look at and talk about Kobayashi's art with her before bringing it back to the team to show them. The camaraderie the two had made caused Shibuya to feel more attached to Kobayashi's work. 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." The work proved more difficult for Kobayashi than expected due to the larger volume of characters she was expected to design for the project. She approximated 5 to 6 main characters and "at most" 10 minor characters to draw for a novel, whereas the number in "Romancing SaGa" was "triple or quadruple" that, with the sequel "Romancing SaGa 2" having even more characters for her to design. When designing for "Romancing SaGa 2", Kobayashi aimed to change things with her approach, but felt that the outcome was largely the same. For "Romancing SaGa 3", she designed the characters to come from different parts of the world based the character's names rather than any design description.
