Rocksmith (2014...I never tried the original). Using a real guitar (or bass) means that it becomes less about playing a game and more about actually playing guitar (or bass). Of all the computerized guitar teachers or “Guitar Hero with a real guitar” things I’ve tried, this one seems to work the best. It is work to learn the songs, but it doesn’t feel like you’re fighting against the software to do so. And like a good teacher, instead of asking you what difficulty you want, as soon as you’re starting to feel comfortable, it pushes you just a little more.
I haven’t taken lessons in some twenty-odd years, but this software makes me feel like I am. In the best way.
