Is good, despite not being as awesome as Rock Band 2. The character creator is definitely more in-depth than Rock Band's, and the exclusive bands are great and have fun charts. I've only played a couple songs, but they were fun, and the charts are better than Guitar Hero 3's. Plus, the music creator, while making sounds that sound like ringtones, is fun to mess around in. It's very deep, and expands the replay value by a mile. The characters are entertaining to watch, the tracklist is great, and it's just fun all-around.

In short, BUY IT. But buy Rock Band 2 first.
