Frets on Fire is an open source clone of the ever-popular PlayStation 2 music/rhythm game, Guitar Hero. And just like Guitar Hero, Frets on Fire features a handful of songs and allows you to play the guitar sections by pressing just a few keys. Instead of using a separate controller to mimic the guitar, Frets on Fire lets you pick up the keyboard and jam in right front of your desk. Best of all, a built-in editor lets you tab any song, spawning a growing community of music-modders on the web.
A brand new game from Tonypa, this one called Keyway and it is a variation on Dance Dance Revolution (DDR) designed for playing with fingers, instead of legs, and using a computer keyboard for input instead of a dance pad.
