Nice write up Alex. I loved Rock Band, it brought a lot of fun and music into my life over the years and made fast friends out of previously politely distant neighbours.
I haven't played RB with friends in a year or more, really, and I only turn it on lately for solo drunken karaoke (its not as sad as it sounds, honest, I hope), but I will always fondly remember the good times the game facilitated. I had laughably poor rhythm and musical sense when I started with GH1, but the RB franchise eventually drilled it into my thick skull, and now I get my fix with Rocksmith and gassing around on my bass.
I still listen to the Harmonix Podcast and I enjoyed the trivia and behind the scenes stuff in this article. Would definitely be interested in more stories, now that it is all over.
