Development of Rock Band 3 began immediately after the release of Rock Band 2 in September 2008. During that time we’ve seen eleven different Guitar Hero installments. Twelve if you include Guitar Hero 6: Warriors of Rock to be released later this year.
Activision seems to be satisfied with over-saturating the rhythm game genre for the past 2-3 years while doing nothing to improve it in any of their twelve Guitar Hero games. What’s new in Guitar Hero 6: Warriors of Rock? A quest mode that tells an “otherworldly tale, narrated by KISS front man Gene Simmons.” Seriously.
