Option 1: Rocksmith
With even a quick bit of research, it seems fairly clear that Rocksmith is the most established "Guitar Hero-like" software available for guitarists who love to game. What's cool is you actually connect your guitar to your computer, and (by sensing the pitch of the strings via a patch cord which converts into a USB input to your laptop), you can play guitar hero in real life!
Then, since it's been built as software (rather than a website), you'll probably find that it runs as a distinct & complete learning environment on its own, with plenty of songs to "beat". By the end of an all-nighter, imagine knowing 10 more songs, instead of overflowing with battle royale adrenaline at 5am.
Give it a try, if you're game for learning some guitar!
Option 2: Phase Shift
Phase Shift is basically Guitar Hero on Steam. Its description states that it's an "instrument focused rhythm game," which supports MIDI devices. So unfortunately, unlike Rocksmith, Phase Shift won't give you the experience of actually gamifying the guitar. Therefore, it's not really an option when it comes to brain-hacking your guitar learning.
That being said, it looks pretty fun to play! And it really throws back to when Guitar Hero first came out.
Option 3: Rustmith
This is a pretty interesting tool, which doesn't look to be super usable, but it's cool that someone's gone ahead and built this. It's something that's been shared via Github, which allows you to interact with a Guitar Hero-like interface (in the most stripped-down form ever), and input your sounds via your mic.
However, maybe it's a bit incomplete, because it doesn't really indicate where to place your fingers to fret the notes, and so on. So it's not usable as a learning tool, and not known if that feature will get added anytime soon.
Guitar Software Versus Video Lessons
These days, there's almost too many learning options out there! It kind of helps to have a limited source of knowledge (to help your brain know what to wrap around), which has great substance. Plus, particularly if you know you're into gaming, then you might want to trap your brain into a guitar game, using your brain's thirst to level-up to drive your aptitude on guitar!
Based on the brief exploration undertaken here, it's clear that Rocksmith seems to be the only software which really does the job; that is, gamify the playing of an actual guitar, making it possible to channel your craving for gaming to learn guitar. The other 2 examples just don't quite cut it, which shows how Rocksmith is still probably the main option available for this purpose.
Software As The Ultimate Coach
As a final word on using software for learning guitar, here are a few benefits of potentially trying something like Rocksmith to learn guitar (as opposed to using websites such as JustinGuitar, Guitar Tricks, or even this site):
- Available offline: you can install Rocksmith on your laptop and bring it to the cottage (which has no internet)
- Complete experience: the main purpose of Rocksmith is to like Guitar Hero online, and it executes that with a library of songs to keep you busy for months!
- Brain-hack: you could approach your learning from a new angle. You never know how well this will work for your brain until you try
