I bought Rocksmith hoping that it would be as good as advertised, and, it's all that and more. I use my Martin and it works fabulously. I've always been a rhythm player and have wanted to learn to play lead riffs. Rocksmith enables you to do that and not have to go through the long, slow process of finding an instructor to go to (and pay). The system interface is great, too. It's a lot of fun. There's an extremely short amount of time needed to understand the interface and just what is expected of you. There's a wide range of songs to play and the challenge is really fun. One of the great things is that you can take a break and it'll remember where you left off. Also, if you're not happy with what you did, you can do it again as many times as you want and that only makes you and your technique improve. Rocksmith is a leap ahead of everything else out there. It's a WINNER!!!
