I think you just plug it into your computer or some shat like that. Me and my friends play on it occasionally, if I had an Xbox I think I'd use XBC before I payed for an online service. As far as lag problems and all that go, we found them to be few and far between. A con that is far more prevalent is that most players on XBC are far better than you'll ever be, but that goes without saying for most online games.
