Raise your hand if you liked Guitar Hero: Green Day. As of my typing, I'm pretty sure no one raised their hand. There's a reason for that: Green Day just hammers the same 6 power chords again and again. Now, there's nothing wrong with that. Hell, I own Dookie (their third album). But it certainly doesn't make for a very interesting guitar game, because there isn't much in the way of variation. The makers of Rocksmith weren't having any repetitive, boring chord hammering in their game, though. The 50-strong song library includes everything from Nirvana to Muse to The Black Keys to Titus. Sure, there are some songs that give you the chance to just hammer on your guitar, but that's because hammering on your guitar is a skill. Well, sort of. But it is absolutely a technique worth practicing. And just like hammering your guitar into pieces, Rocksmith provides songs specifically chosen to practice specific skills. There are blues songs to practice your scaling and hammers. There are metal songs to practice your crazy solos. There are some more off-beat things to play around with your um... off-beating? I could go on, but you get the point. Rather than just choosing a ton of popular tripe to sell the product, Rocksmith chose songs that are both enjoyable and varied enough to give you the most out of your game. Those songs aren't just a bunch of crap either. I hadn't heard many of the bands on the soundtrack, but I can tell you right now that I'll be looking them up and buying to their next show near me. And, if you simply aren't satisfied, there are dozens of songs available for download.
