This is really very simple: If you are a fan of Green Day's newer material (i.e. "American Idiot" and "21st Century Breakdown" albums) get this game. There are some excellent tracks from older Green Day stuff you might find you like, but there's not enough of them to hold the attention of of pre-American Idiot Green Day fans. Everything works as you'd expect, with smooth presentation and animations, and the inclusion of vocal harmonies are a nice idea carried over from The Beatles: Rock Band. There are a ton of pics and interview unlockables, but why you'd look at any of them more than once is beyond me. I mainly play guitar, and as someone who just made the switch to the Expert difficulty level a couple of months ago, almost all the songs hit that sweet spot of really fun, but just challenging enough. The reason I'm giving this a 7.5 is because of it's limited appeal. If you just really don't like Green Day, I have no idea why you'd even be reading this, so it goes without saying this game isn't for you. If you're on the fence about it, I would just borrow it from a friend, rent it, or wait several months for a price drop. But, if you're a mega-fan who, like me, enjoys ALL of Green Day's material, this is a no brainer.
