Ever since wannabe shredders picked up plastic toy guitars to play Guitar Hero, the legitimacy of music games has been in question. What's the benefit? Why not play a real instrument? I always feel like I have to point out that video game guitar and real guitar are totally different, separate skills. With the Fender Squier for Rock Band 3, the line has not simply been blurred - it is erased. I have begun to learn the way of a six-string samurai.
