Rock Band surpasses $1 billion in sales in North America
Rock Band has surpassed quite a milestone, the game franchise has sold for over $1 billion in North America since its release in 2007, according to NPD (who else?). The $1 billion number is for retail only, and excludes DLC. NPD also revealed that GH has sold over 40 million tracks from the Guitar Hero store as well.
Rock Band’s main competitor, Guitar Hero, has already surpassed the 1 billion mark — a feat which it accomplished over a year ago.
