Rock Band 3 offers a substantial upgrade to the rhythm game experience, boasting an impressive on-disc song selection and exciting new modes for both casual and dedicated musicians. The introduction of keyboards and vocal harmonies adds depth to multiplayer sessions, and the beginner-friendly tutorials make it great for parties. The Pro Mode, with its focus on real instrument emulation, marks a significant technical leap for skilled players. However, those without new instruments may not find the core gameplay vastly different from previous entries, and some players might find the Wii version's simplified visuals a downgrade.
