GameSpy writes: "Lego Rock Band is a bit of an odd experiment. At its core, it's exactly Rock Band, with only two notable additions. First, you can no longer fail out of a song: Play badly and you lose your accumulated points, but you just need to play another passage correctly to get back in the game. And two, the game now includes "Rock Power Challenges," in which the entire band shares one performance meter, and the different sections drop in and out, putting each player on the spot. It's an interesting feature but nothing terribly revolutionary; in comparison to the clever multiplayer modes in Guitar Hero 5, for example, it feels a bit lackluster."
