A month or two ago there was a thread discussing the value of the game as guitar instruction. Opinions were mixed as are reviews on the 'net. There did seem to be some positive comments about such usefulness once equipment tweaks were done to compensate for the delay between playing notes and speaker sound. Others thought the lack of flexibility allowing progess within the game a hindrance....

Darned if I can find GT thread. If others can't help out, I suggest a Google search of Rock Smith reviews.
