Well, the franchise was gaining momentum, but I don't really think that can be attributed to just being on the 360, I don't think the install base was that much larger at launch than Halo 2's was, though I could be wrong. Do I think the game would've increased sales if Microsoft didn't advertise it like there was no tomorrow? Probably, but I think the ads convinced a lot of people that this was not a game to miss. Of course, then you have word of mouth, which has given it legs for two years now, also elevating it into the stratosphere now, over 10 million.
