For starters, we went to the Backstage area before jumping into the gameplay. The only option we had was to go into the Rock Star Creator, which shows you the pre-made characters you can select from (with many familiar faces, if you're a GH veteran), as well as a Custom selection for making your own rocker. Again, much of it is disabled for the demo, but it gives you a idea of how much you'll be able to tweak and tune (and what can be altered) to get your own musician to look just the way you want."
