Frets on fire is pretty much a better version of Guitar Hero for the computer. Two of the main differences is that with FOF you use the keyboard instead of a fake guitar to play the game and you can make/edit your own songs to play along with which I thought was pretty cool. FOF is free and open-source so you don't have to dish out 100 bucks for the game and controller. This game is very fun and very addicting due to the fact that your not limited on what songs you can jam to.
