Games like Guitar Hero were once massively popular but developers seem to have moved on, thankfully there's Clone Hero which is a free game based on the idea. Available cross-platform with support for Linux, macOS, Windows and Android. You can play it with any 5 or 6 fret guitar controller, any midi drum kit, any game controller and even your keyboard.
After being in development for 3 years, the big 1.0 release is finally here. The creator said it will now go into long-term support mode for bug fixes, but no major new features as it's finished and complete.
Some of what's new includes: worldwide public servers for online play, drums support, more customization options, player profiles added a bunch of new features, new gameplay modifiers and much more.
