The Guitar Hero franchise continues to produce for game publisher Activision, accumulating $100 million in North America since its launch on Oct. 28th.
Updates:
For comparison's sake, Halo 3 pulled in $300 million worldwide in its first week. To be fair, Guitar Hero 3 is only available on North American and will not be released in Europe and Australia until later this month. The game is also available across 4 platforms, while Halo 3 was Xbox 360 exclusive.
