Harmonix was "terrified" while making The Beatles: Rock Band
Development on The Beatles: Rock Band had members of the Harmonix "terrified" according to John Drakes.
These feelings of trepidation were present throughout development despite the firm being chosen by Apple Corps to do the game, thanks to the firm's reverence for the subject matter.
"I don't know what Apple was considering before they started working with us, and I'm sure that there were conversations on both sides [with Activision]," he told CVG. "I think they saw that we were the company with the most reverence for what they were doing - we're not looking to turn a quick buck on The Beatles. This is something we've loved and respect and would not want to screw up.
"We were terrified while making the game, hoping we don't make them mad at any point - they're really nice and easy to work with, but this is The Beatles, you can't afford to mess this up."
Drakes also goes on to talk about criticism from bands regarding music games distracting kids from playing real instruments, and the process of getting the remaining Beatles and George and John's widows involved.
