How about another free game? This time the game is Frets on Fire. This game is very much like Guitar Hero, except it’s played using your computer’s keyboard. This game has all kinds of great features. First, it supports guitar controllers, so you don’t actually have to play with your keyboard if you really don’t want to. The game also contains hundreds of community created songs, it has a song editor to create your own songs, and it supports the importing of Guitar Hero 1 and 2 tracks. Oh yeah, and it’s Mac, Linux, and PC compatible. This really is a great one.
