Possibly! The last time I played, I didn’t run into a single person, which was kind of a bummer. I have the white cloak so it’s fun to guide people through whenever I find someone new. I also discovered the other day that the actual music changes whenever there’s another player. The composer of Journey, Austin Wintory, has a great series of videos where he annotates the sheet music of the official soundtrack. The one for Threshold mentions this.
