"When Rock Band's price of $170 was announced in the middle of last year, many people wondered whether anyone would be willing to put up that kind of money up front for a game. With a consistent spot on the top sales charts, the answer was apparently yes. Why did Rock Band do so well? It's simple really; music brings people together, and Rock Band is a game all about forming a band and making music. It had all the elements in place to be a huge hit and it turned out to be just that. Since the game's release though, maybe fans have been giving feedback on what could have made the game even better. We're roughly a year from the release of the original, and most of these requests have been taken to heart in Rock Band 2."
