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.
XBL Gold enables you to play games online (multiplayer) as well as other premium features (Netflix, Hulu, etc.). If you just want to play games locally, you don't need it.
