U2: Rock Band?
“We definitely would like to be in there, but we felt some of the compromises weren’t what we wanted,” bassist Adam Clayton tells USA TODAY's Edna Gundersen. “That could change. I love the idea that that’s where people are getting music, and we’d love to be in that world. We’ll figure something out. What The Beatles have done, where the animation is much more representative of them, is what we’re interested in, rather than the one-size-fits-all animation. We didn’t want to be caricatured.”
Since they seem to care a lot about the integrity and authenticity of their music, Guitar Hero: U2 would be out of the question.
