It was a hit at the RB party I threw, and the auto-kick pedal is a nice option for playing with younger kids or uncoordinated folks.

There are parts of it that feel nice, like 1 song pick-em set lists in story mode, star tracking (I have a PS3), the Rock Power Challenges are cute, and it just feels smoother to play for the most part. I miss some of my DLC and the RB2 songs, and I'll probably go back to playing RB2 eventualy, but it's fun enough that it will stay in my library for another month or so.
