An all around oringal masterpiece, which deserves nothing less then a Solid 10.
The second distinct experience here is the group dynamic. While the Guitar Hero series hinted at this, Rock Band fully embraces the idea by gearing all the songs and the brunt of the new gameplay at people who are playing together. A lengthy and varied World Tour mode lets you build a band from nothing into the next big thing. Even the moment-to-moment gameplay is geared towards unison playing and cooperation, and each band member can save the performance from disaster by yanking failed instruments back in. It's only disappointing that, as of launch, online play doesn't include the full World Tour.
