I've seen a lot of Guitar Heroes clones that you can play online, and for Windows, but to be honest, most of them suck. Frets On Fire however, is an amazing game! It’s available on Linux, Mac and Windows, and (For Linux) is just as easy as downloading, and executing the main Shell script to get it running.
Install the full package from http://fretsonfire.sourceforge.net
Extract the files, and run the main Shell script to run!
- Its as simple as that. Perfect to store on your USB stick.
I had a few problems when first running this game. I found out that if you disable your Compiz before running, it resolves the problems.
