Summary: Comparing original rocksmith to the new one, let me just say I like them both, I started off buying the newest version first and played that for a could week, I love it and feel I was learning a lot from it, but felt like it lacked a little direction in structured progress which is what I saw people...
Summary: This game is really fun and quite effective at teaching you to play these instruments. I have years of experience playing bass and absolutely no experience playing guitar. I have found this game to be helpful for me with both instruments.
Summary: What an awesome way to learn guitar. This version is also for the bass. It makes learning fun and offers abilities to work on sections of a song that are giving you problems. This is NOT like Rock Band or Guitar Hero, this is more of a learning aid.
Summary: The learning curve is a little steep for newbies, but after a little bit of practice it isn't too bad. I love the gratification you get from not only learning to play the guitar but also to complete levels and playing the game. I was amazed at how well the interface cooperated with the guitar.
