Here’s what Kotaku has to say about the new Rock Band 3:
Rock Band 3 offers something for every type of rhythm game player.
For the more casual aficionado of music mimicking, Harmonix and MTV Games deliver a more streamlined interface that makes Rock Band more party-friendly than ever. For the hardcore plastic guitarist and drummer, Rock Band 3 puts the challenge into overdrive, with a legitimate music instruction tool for wannabe musicians looking to learn the fundamentals (or their favorite songs).
Add keyboards, vocal harmonies and a strong, diverse soundtrack and we’re ready to certify this one double platinum.
