I was looking at presents for my nephew and someone suggested getting him an xbox 360. I looked and they are 199.00 for the console and a controller. What else is needed for this system to work? Do you also have to buy games? And what is the xbox live thing I saw that was 50 dollars? I know nothing about any of this stuff. I did see it says they are wireless so I assume you can connect to the net through a router?
