Harmonix co-founder Alex Rigopulos has said that you won't be able to make your own music in Rock Band 2.
This is a key feature in rival game Guitar Hero World Tour, but Rigopulos said it was the sort of mechanic Harmonix would rather take time over than rush.
"We really felt like we wanted to do it right," Rigopulos told Associated Press. "We're taking a radically different approach to that problem. It's something we wanted to take more time to do it right.
"It's actually something we're not focused on in Rock Band 2. We're really focused on other areas related to the music and bringing the community together."
