I’m sure die hard fans of Green Day will have no problems picking up the game, similar to how Beatles fans naturally picked up The Beatles: Rock Band, but without more extensive DLC support, it might be hard to pick the game back up after playing it several times. Don’t get me wrong, I appreciate what Harmonix wants to do with Green Day, making it a complete stand-alone experience.

You can, however, export Green Day: Rock Band onto your hard drive and play it through Rock Band 2, just as you did with Rock Band 1. Also, any Green Day DLC you’ve previously downloaded for Rock Band can be played in Green Day: Rock Band.

Green Day: Rock Band will render you into another American Idiot on June 8, 2010 for Xbox 360 and PS3.
