Lego Rock Band Coming to PS3, Wii and Xbox 360
There is no typo in that headline. Lego and Rock Band are joining forces in Lego Rock Band which is currently in development at TT Games in partnership with Harmonix for PS3, Xbox 360 and Nintendo Wii.
Lego Rock Band is targeting younger and family-centric audiences who might have shied away from big brother Rock Band.
The use of Lego in Rock Band will allow players to “build” their band from their own personal avatar to the manager, crew and even roadies. Expect Lego’s trademark humor found in previously licensed properties to make an appearance as well.
