A fantastic product that is actually kind of bad at doing it's job. It's essentially Guitar Hero with an actual guitar. The issue is there aren't as many learning tools as there needs to be. The biggest one that is missing is a metronome. If you are actually a beginner, as in the first time you laid hands on a guitar was when you bought one for this game, do not rely solely on this game. Watch some videos and find a good community to talk to. Also playing through HDMI audio introduces heavy latency so make sure to find some videos to help with audio set up. Get yourself an amp and a tuner and practice outside of the game. Use this tool as just that, a tool.

Other than that Rocksmith is great. Once you have everything setup, Rocksmith plays like dream. I personally don't like the way it tries to teach you the songs by drip feeding the riffs based on how well you're doing. But that is entirely because I was an intermediate player when I began playing. The way I was taught to play was to keep going after you've made a mistake and try to improve as you go. This is difficult to do when the game takes away bits of the song if it feels you're having trouble. So I will make a mistake, the riff will simplify which throws me off causing me to make more mistakes and simplifying the riff even further. I turned that off immediately.

The best tool this game has is the riff repeater. You can pick a section of the song and play it over and over. You can set the speed of the riff and the game will speed it up once you get the hang of it until it gets back up to 100% speed. The songs included are a pretty good spread. Got some Metal, some Punk, some Blues, a little Pop, even some Hip Hop.

All in all Rocksmith is probably the best guitar learning tool there has ever been because the best way to improve your playing is to play along with the song you're learning. This gamifies it.
