I have the rocksmith game for PS3 and enjoy the arcade more than the included song library. 

I think it is a fantastic leap beyond guitar hero since it utilizes a real guitar. 

I am looking for the next technology leap which uses digita information as rocksmith audio tracking is still very limited in its accuracy. For example, Rocksmith is rewarding most of the time as long as you hit the right pitch regardless of which string ou play or where on the fretboard you play it.

I am also seeking what would be the complimentary/opposite focus of Rocksmith i.e. 5% entertaining me and 95% training me to entertain.
