This fills you with an emotion that can only be known as 'FUCK YES'. It amuses me too that not a week ago my friend and I were dicussing the potential for epic win that would come from such a game.
Apparently too, according to the wealth of nerdish infomation that is my bother, they're making a Lego Rockband game. I can't wait to see it :D
(yes, I'm a Lego nerd. Comes with the family XD)
