In "Star Wars Jedi: Fallen Order," Journey + mode allows players to replay the game with all the abilities, skills, and lightsaber customization options they've unlocked. However, Journey + does not change the overall mechanics of the game, such as the inclusion of the "Stir Mode." The main difference in Journey + is the ability to carry over everything from your previous playthrough, while still facing the challenges of the game again.
Are you referring to a specific aspect or feature when mentioning "Stir Mode"? If you can clarify what you mean, I can provide more details!
