If your gonna add substance sales from the xbox you should also add all the Halo Pc game sales. And remember, Halo CE was a launch title with very little promotion in it. Microsoft actually had their marketing machine bet on Oddworld Munch's Oddysey at the time. The Halo community developed largely by word of mouth and was underground for the most part until Halo 2. Halo was a hit, not by fancy marketing but by the gamers. Similar to many blizzard games. And you cant buy marketing like that.
