We can only assume that Forbes lives in a world with no GuitarFreaks. In the latest issue of the business magazine, a biographical profile of Activision Blizzard CEO Bobby Kotick turns controversial when it accuses Rock Band of ripping off Guitar Hero. According to the magazine, "EA also teamed with MTV to sell Rock Band, a shameless knockoff of Guitar Hero that added drums, bass and a microphone to the world of make-believe rock stars."
Leaving aside the fact that Guitar Hero hardly represents the roots of its genre, such a brash statement feels distinctly at odds with the rest of the (pretty neutral) piece. There's also the role of Harmonix to consider: after all, theirs was the name behind both franchises!
