Harmonix' Greg LoPiccolo wants you to know that he's thinking about you. He knows that as you play Rock Band, the song that you'd really like to play and spread across the world is your own band's tune. LoPiccolo wants you to know that he wants The Cephalopods' local hit "Three Is a Tragic Number" in the game as much as you do, saying "We would like to make it possible for people to introduce their own music into the Rock Band ecosystem, which is a pretty complicated topic."
Some of those plentiful complications include IP issues and ratings problems, but LoPiccolo still thinks it's the "natural direction" for the franchise. He also talks about the feasibility of a keyboard peripheral for the game. Can we just be the ones to point out that he's missing the obvious? Keytar, people. Keytar. It's staring you right in the face. Pull the trigger on the fun gun. Do it.
