Back when Harmonix announced The Beatles: Rock Band, the general consensus was "duh, it's The Beatles." That game was expected to be a special love letter to the most influential band of all time. Love them or hate them, this is hard to deny, and Harmonix pulled off one hell of a game.
So when Harmonix announced that their follow-up to The Beatles: Rock Band was going to be a special love letter to Green Day, many fans were left scratching their heads. Why would Green Day be receiving so much attention? Whereas The Beatles have an almost universal appeal, Green Day's audience is more limited. Would people even care? Being shown the game, it looks like Green Day: Rock Band will not be nearly as grand in scope as The Beatles, but for fans of Dookie, American Idiot, and 21st Century Breakdown, it should be more than enough. While not a bad thing, there are certain elements to consider.
