Guitar Rocksmith is really nothing more than a teaching game that teaches you how to play a guitar. It's basically inspired from the very first guitar games that have produced some very good players. Do you need a guitar instructor to learn guitar?
If you want learn how to play the guitar, you should check out Guitar Rocksmith, but if you're just like most students who are serious about playing chords, you're probably wondering what kind of guitar should you use. Well, we did some digging and found that it works for any guitar that has six strings. If you know something about guitars, you already know that all of them have six string in the beginning and only lose some strings as a player overuses the instrument.
With that being said, if you're serious about learning to playing the guitar, go buy a guitar now at your nearest music shop. Don't over think the process, just ask for a recommendation from the shopkeeper and you should be good to go.
There was a time when I tried to learn the guitar but never really got around to playing one song properly. It wasn't that the teacher was good – he was good actually. But I guess I'm just one of those people who loves guitar but have the misfortune of guitars hating them.
But I might just try to learn again with these guitar games. At least I won't be paying some teacher hourly fees. I can just sit in front of the computer and learn how strum and pick. It should come easy to me when I finish 10,000 hours of practice (that's about the time that it takes for anyone to become an expert at anything). But first let me buy a guitar from that music shop around the corner.
