I was skeptical that a video game like this could actually improve your skills at playing a guitar, but I was proven wrong. I bought this with literally zero experience with a guitar before in my life (with any musical instrument, for that matter). Videos and reviews online got me interested in what it can do, so I jumped on it during a sale—but only after I found a decent, budget-friendly beginner's electric guitar to buy for myself as well (if anyone reading this is unsure by now, the game requires a REAL guitar and does not come with one). That may make it sound like it's a big investment for just a video game that may or not may live up to its promises, but it's nowhere near as expensive as, say, private guitar lessons or classes. I was surprised with my progress with a guitar just by playing Rocksmith. I played every day for about an hour, sometimes more, for almost a month. Coming from zero experience and skill, I became comfortable with both of my hands and playing basic songs without always having to look down at my hands. Due to getting busy with life, I stopped playing regularly thereafter for more than a month, and I lost a lot of my progress. I had to decrease difficulty a bit when playing Rocksmith then, but the game recognized that I didn't have full mastery of certain basics at that point and thus didn't increase difficulty steadily pending my performance but rather "stayed with me", so to speak. Just goes to show that the game can improve skills, at least for a complete beginner, but only so long as you put in the time and practice, just like with everything else. It's really fun, too, so it's easy wanting to play this game regularly!
