Tuckstir I love Playing Rocksmith.. and WAS using it too learn playing guitar... which is not all that great.. for the simple reason that rock smith doesn't show you easy to use shapes, when playing arpeggios. ect
Yep there are definitely limitations. I used it to start playing bass without an issue but I'm sure a bass teacher would send me back to school ?
Rocksmith doesn't really teach much theory. They have the videos and that's great but it's no replacement for a teacher.
One feature I only just now found (3 years later) is that when you have a song open, you can see all the chords in the song. That's a very handy feature because getting the chord shapes under your fingers can help you with a) some of the licks that are formed from the chords and, more importantly b) familiarising yourself with song structures, which chords go well together, which chords you enjoy the sound of, etc.
Only parrot-learning with Rocksmith —or any other method— is the devil! You'll lose whatever you learn as soon as you stop. (Which is what happened with me. I got Rocksmith to play more but, as every time I took a break for a few weeks, I had to almost start over.)
