The first Rock Band revolutionized the way music games were played; however, its sequel is more of an evolutionary step forward. A huge song list and the ability to play World Tour mode online are the biggest attractions--very little else has changed. It's more of the same, but it's still awesome.
* 80-plus songs on disc
* Ability to import songs (for a $5 fee) from Rock Band
* Online World Tour mode
* Great gameplay is a blast alone or with friends.
* Very few significant changes since the first game
* Some songs aren't much fun.
