I started to play guitar after 20 years when I first saw rocksmith 2014 from a friend and since nearly 1,5 year I am playing rocksmith. 4-5 days a week when I got back from my job after I eat my dinner and talk to wife and kids 1 or 2 hours before going to bed I take my guitar and start Rocksmith. Then I list the songs according to mastery level. I play a song that I never played (0% mastery) before and finish it lets say 64% mastery. I choose the next song with which is 65% mastery and try to improve the mastery score until I reach a better score then before and continue next song with improved mastery . This loop continues until I reach a song which i improve 80% or better. Then Return to 1st step. My goal is for the time being improve any song to %80 or better mastery then I will continue to 85% , 90% . Its fun and challenging sometimes. Up to now I think I reached more than 200 songs which are 80% or better. But my Guitar teacher told me that Rocksmith is waste of time because only with playing songs you can never improve your playing. In one way i agree with him because without rocksmith if I take the guitar to my hand I don't know what to do. Even I can not play a song from from beginning to end without any scrolling notes in front of me. I can not memorize the songs with exact chords and solo since I get used to play with game. This is the biggest dilemma for me play guitar with rocksmith and have fun or sticking into practicing scales,drills and riffs .
