Ask me tomorrow and I'd probably give you a different ranking. I absolutely love all 3 of these games and it's my dream to own all of them.

Still a great game and I like the band somewhat, but there's just something about rock band pins I don't like. Probably listening to the same songs over and over. IM (and ACDC) are great games but I wouldn't want them in the home environment personally.
