Guitar Hero's history may not be as long and storied as Aerosmith's, but the young music game's popularity and commercial success has propelled the series to comparable stardom: North American sales alone are worth over a billion dollars; the band who wrote the third game's end song, Dragonforce, enjoyed a 126 percent spike in CD sales the week after the game came out; and there's even a whole South Park episode about it. Spin-offs, then, were inevitable, and Guitar Hero: Aerosmith aims to be the benchmark.
