The limited edition Halo 2 will contain a free 2 month trial of XBL. Although you will most likely not have voice capabilities unless you have a communicator and an adapter, it will be fun to just try it out. Plus headsets on their own are like 20$ as opposed to buying the starter kit which runs 40 or 60. So don't fret over getting your XBL account up, because you will get a free one with the limited edition. As for the regular edition, I'm not quite sure.
