Writer Jennifer Svedberg-Yen drew inspiration for Clair Obscur: Expedition 33 characters from a NASA simulation she participated in where she acted as an analog astronaut on a mission to an asteroid.
The game includes characters like Gustave, an engineer; Sciel, a farmer responsible for meals; and Lune, wielding elemental magic powers. The characters' roles were influenced by mechanics, world-building, and space mission staffing.
Expedition 33's structure challenges traditional RPG norms by not having a clear main character throughout the game. Each act shifts focus to different characters such as Gustave, Verso, and Maelle, providing unique storytelling perspectives.
While it's uncertain if there will be a sequel, Svedberg-Yen views the game's story as a standalone success with a well-connected beginning, middle, and end, leaving room for player interpretation and creative expansion possibilities.
