Parents would be my guess. Who don’t want a TV or gaming system in a kids room but would like to allow them to play games while a sibling or parent is using the TV.
Bought it when it first came out to continue playing with my friends who played from Destiny 1. It got old really quick. I didn’t really enjoy it as much as the first game and I was really confused by the lack of character building in game. It felt really directionless after finishing the main quest. And I learned pretty quick that I wasn’t attached to any of the in game characters the same way. So I quit playing after about a year. Never picked it back up.
