Thus far, there have been three variations of the Xbox released in the United States. These variations are mostly notable for their pack-ins, as the component level elements have not changed much. The first series Xbox was packaged with no games and the larger Xbox controller. The more recent incarnation of the Xbox has two pack-in games (on one disc), and the smaller S-Type controller. There is now a green Xbox, dubbed the Mountain Dew / Hulk Collector's Edition, as well as a translucent green Halo Edition Xbox.
