I just got an Kinect XBox bundle and I plan to use it for all the dancing games and workout games. I am not an extreme gamer. What is the purpose of this membership? Do I need this in order to use the free codes that came with my games? I don't watch movies or plan to stream. I don't plan to use Facebook or twitter on the Xbox. I am trying to figure out the benefits of this membership. I can't find anything on the internet other than people claiming they need it to stream movies and connect with online gamers. I don't plan to do that so are there any other features that make this worth a purchase. BTW I also have a PS3 and Wii.
