Rocksmith 2014 is not only for beginners who want to learn how to play, but also for fairly experienced players who wants to improve their skills or simply take advantage of the many tools in-game.
There are several modes:
''Learn A Song'' which allows you to play along to one of the songs that are included in the game or can be bought as a DLC. It might be remind you a bit about games like Guitar Hero. The difficulty adapts after how good you are, and get harder and harder as you learn more and more.
''Session Mode'' gives you a virtual band to play with! You can customize and choose your scales, tempo, groove, atmosphere (club, studio, arena) and what instruments that is in your band. Or you can load up a stock one, like ''Electric Blues'' or ''Psychedelic Rock'' all after what music you intend to play.
There are also a whole catalouge of lessons that learns you everything from playing chords and the basic scales (and even how to hold your guitar, lel), through harmonics, hammer-on's and pull-off's, to the master classes.
Also there are arcade style mini-games that let's you train on your tecnhicques. Temple of Bends, Scale Warrior and Harmonic Heist are some examples.
Along with that you get some very useful tools. The tuner which allows you not only to standardize your tuning, but also change into different tunings based on the song you are playing. So it might be smart to plan ahead so you aren't stuck too long in the tuner. Also you get ''Tone Editor'' which allows you to change your effects, pedals and amps. Coolest product placement ever with Eden, Orange and Marshall. Every song that you play also have an ''authentic tone'' that loads up when you start the song. If for example the solo and the riff has different tones in a song it changes automatically. You can also load up these in Tone Editor so you can play with it in Session Mode.
The included songs ranges from hits like ''My Generation'' and ''We Are The Champions'' to songs from underated indie bands that no one has ever heard of. Try to play every song, you might find something you like. If you have the original Rocksmith you can import them with updated tabs or you can buy it if you didn't own it previosly.
Looking at the large amount of DLC, it's easy to think of this as another ''DLC: The Game'' but it isn't. New songs are released to this game constantly, but the artists need to be paid. So you have to pay for the license.
If a song you like hasn't been released however, you can download custom songs for free using some modding tools. They might be faulty however since they are made by sparetime modders.
There are some things to remember though: This is not Rock Band or Guitar Hero. You might and should have fun while playing this game, but remember it's an educational game. This means that you can't expect to learn the songs by playing it over and over again. You have to go deeper and use the ''Riff Repeater''. Riff Repeater allows you to slow down certain sections of a song and play it at any speed you want, again and again until you get it.
Also this is a TOOL not some kind of potion that magically transforms you into Jimmy Page. The challenge to take the skills you learn in the game into the real world might be tough. Sometimes you will find yourself cutting shortcuts just to hit the notes, which makes things even worse (espescially when soloing). If you really want to learn, you are gonna have to use other means too.
In short: It is a great game if you want to learn the basics of guitar/bass, improve your skills or just have some fun. Use it with caution and don't rely solely on it if you want to learn guitar properly. Great songs, good tabs and useful tools. It's worth buying for every aspiring or aspired guitar player out there.
