"Star Wars Jedi: Fallen Order" is indeed set within the Star Wars timeline, specifically between "Episode III: Revenge of the Sith" and "Episode IV: A New Hope." The game follows the story of Cal Kestis, a young Jedi who survives Order 66 and is on a quest to rebuild the Jedi Order while evading the Empire.
While "Fallen Order" is primarily a video game, it features a narrative and cinematic elements that closely resemble those found in Star Wars films, including character development, a rich story, and impressive visuals. You could certainly discuss it in the context of Star Wars storytelling, but it is not classified as a movie. It exists as part of the broader Star Wars canon and contributes to the overall lore of the franchise.
If you want to consider it in relation to the larger Star Wars story, feel free to discuss its themes, characters, and events alongside the films!
