Week 3 update (because I know you fuckers care): Really enjoying it. Biggest hangup (besides skill) is trying to get the music theory behind everything. And on top of that the physics part of it. I've had three lessons with the instructor and the last session I brought in my laptop and showed him rocksmith. His response was that he would be purchasing it that night (since amazon had it for $30 off). I've started to develop the callus on my fingers, mainly the left index, and overall my hands aren't complaining anymore. I found a feature on Rocksmith that has you play songs back to back for a specified period of time. Really nice when I don't feel like doing the technique games or working on a particular song but I want to do at least a 20 minute session. I've noticed that I'm starting to notice when I'm strumming too hard for the song and can dial it back a little.
