Just like on Guitar Hero, there are things that are similar and things that are not similar at all. When I first played DJ Hero, I wasn't very good. The control surface is similar in some ways to a turntable, but in other ways not at all the same.
DJ ShadowMy main thing is constantly looking forward and trying to make music that I couldn't have made at any other time.
DJ ShadowI would agree with you that there's 90% imitation and 10% innovation. That's true of any genre.
DJ ShadowYou can be a great DJ and still be not very good at DJ Hero. And vice-versa: You can have never spun in your life on real turntables and be fine on DJ Hero.
