It’s a Story-Based Experience, Without Moral Choices
Most of the Star Wars games of recent memory have been either multiplayer-focused titles or smaller mobile gacha-style games. Jedi Fallen Order is a huge break from that trend with a heavily story-based single-player experience.
You play as Cal Kestis, a young padawan on the run from the Empire, trying to re-establish his connection with the Force. Although Fallen Order is a single-player game, the big thing to keep in mind is that it doesn’t mean there are moral choices.
Respawn wanted to tell a very specific story about a strongly-defined character from the start. There’s plenty of drama and character development, just don’t go in expecting to make a choice between the Light and the Dark side, like in the Force Unleashed or similar games.
