"What would parties be without the original Rock Band? A bunch of schmucks sitting around a bowl of half-eaten chips, listening to each other's playlists, that's what. Instead, thanks to Harmonix's brilliant rock n' roll four-way, parties have been transformed into awesome jams of fake rock stars breaking each other's furniture and melting each other's faces.
Fast-tracking a sequel to RB was a no-brainer but would pop culture oversaturation and a "same old/same old" factor taint the new game? Nah. Rock Band 2 keeps what was awesome about the original, improves what was wrong (mostly) and adds a bunch of quality upgrades (including a hefty online component) that keep the rock alive."
