Rocksmith is the first music game to use an actual instrument. It’s about time, but the fact is, Rocksmith just doesn’t work as well as it should. The gameplay works like a regular music game. Notes from the top of the screen trickle down to the bottom, and players try to hit them. The kicker with Rocksmith, aside from the fact that it uses an actual guitar, is the dynamic difficulty which progresses as the player does. However, there is a considerable amount of lag which hampers things a bit, and the calibration tool in the game is awful.
