The Rock Band franchise has been a breakthrough in the music game genre, but not always with family friendly songs like “Sex Bomb,” for instance. Lego Rock Band is here to solve that problem. You can basically sum up Lego Rock Band by adding more family friendly songs, and converting everything in-game to Lego. The only difference with this version is that you collect Lego Studs every time you hit a right note, and you will be able to use these to unlock in-game bonuses such as new avatars and other accessories.
This is a great way to introduce all ages of the family to Rock Band but might be considered a little over the top to everyone else. The game will be available on Xbox 360, PlayStation 3, Wii, and the Nintendo DS this holiday season. Source (Joystiq).
