I love the idea...

I just bought my son an Ibanez Mikro. Personally, I do NOT subscribe to the "learn acoustic first" concept...I think it leads to frustration as most starter accoustics are peices of crap...

Anyway, I am teaching him basics...He is 10 years old and asked me to give him lessons...

This Rocksmith looks to be a fantasic idea...I am interested in playing it too...I am sure we will learn a lot if we dive into it...Not sure when we will dive into it as we don't have an Xbox or PS3...So it might have to wait...

I purchased it the day it was released and tried it on my old Fender Squire Strat.  I previously had the Rock Band Pro Guitar but it was hard to tell if my fingers were on the same string as all the buttons felt exactly the same so I never really played with it much.  Since playing it I have upgraded to a Ibanez RG2EX2 and a Line 6 Sipder IV 75 Amp with FBV Pedal.

With Rocksmith I was able to plug in and start playing songs right away.  Of course most were single notes but I quickly advanced up to playing chords.  Having very little experience as a beginner guitarist I felt like it was pretty cool.  And after having played every Guitar Hero and Rock Band game I guess it was time I learned the real thing.  There are lots of mini games that seemed fun to help you get used to moving around the fret board and changing notes.  Cool zombie game that gets you used to changing chords fast.

Over all I don't know alot about guitar but Rocksmith seems to be a very good step into introducing the video game generation into guitar.  The only complaint I had was the song lists.  A lot of them I have never heard of or are B-sides to popular artists.  But the songs I have played were fun to play and I grew to like them for the most part.  (There are also downloadable ones coming I think.)  But I take it for what it is.  Gutiar Hero and Rock Band introduced me to many many songs I would have never listened to on my own and I am thankful for them. 

For the moment I have paused playing the game and started working through http://www.justinguitar.com/index.php to learn to actually play.  Once I started learning my chords I went back and started trying to learn the entire song of Can't Get No Satisfaction.  I was surprised how well I was doing till I nocited my index finger felt like a razor blade cutting through it from changing the chords so fast.  I looked down and my finger had turned purple and had a deep gouge in it.  So I am taking it easy now till I can get used to switching chords without using so much pressure. 

Overall I think it's a great supplement to real or online lessons.  The lessons help develop how to play and the game provides some great songs to play along with.
