Question

Do you have to be a gold member to play games online on xbox live?
Hi I was wondering if you have to be a gold member to play game on xbox live because I just got Modern Warfare and when I tried to connect to online mode it displayed a message saying that you do not have the right account to play online.

Answer

Yes. A gold account is required for online play.
