A few of the short comings are rearing their ugly heads now I have had the game for almost two weeks. Unless I am dumb, I am sure there is no option to tune the guitar once in the Guitarcade. I was having a blast playing Scale Runner but after half hour or so a couple of strings weren't quite as accurate. Had to quit the mode and re enter.
Also, as someone said to me above, the game does move a bit too fast. I have hit a brick wall on a couple of songs. Glad to have discovered I can edit/remove/add songs to my Event which makes it a little easier, provided you haven't done well on them previously. Nirvanas Breed I need 90k to qualify after just hitting 65k in the single song mode.
Still, enjoying it immensely, even been reading some tabs online (Learning Def Leppards 'Switch 625'* instrumental at a very healthy pace.Just need to be more consistent in the lead now.
Hope RS2014 has some Black Sabbath songs, they are very fun to play.
