Its aight. Basically uses the same kind of formula that Beatles Rock Band did, except somehow gives even less context about the band. You definitely have to already know about Green Day beforehand to get any enjoyment out of the bonuses this game has. At least Beatles had little descriptions for everything so even those not in the know can learn a thing or two, but those are absent here. The other major problem with this game is the inexcusable fact that a portion of the game is locked behind DLC, which is now no longer purchasable. The game has 3 main albums that you play through: Dookie, American Idiot, and 21st Century Breakdown. However, a portion of 21st Century Breakdown's tracks are DLC, so the album challenge for that section of the game is locked away unless you buy the DLC (which you can't by now.) Also for the difficulty freaks for these kinds of games, Green Day music makes for pretty samey basic beatmaps, so hardcore guitar shredders won't be very satisfied either. With all of those problems, why do I still think this game is alright? Simple. I like Green Day.
