Have you noticed the seemingly unending buzz around the PlayStation 2 game Guitar Hero? If you don't have a PlayStation, but are curious about that type of game, you might like to check out Frets on Fire, a free guitar-themed music game for Windows and Linux. Although it doesn't feature the licensed popular music that the commercial name-brand game contains, it still has some pretty hot tracks and frantic gameplay.

The game has some serious attitude, the likes of which you won't see in most (but not all) retail games. It's not graphic, but the language in the game could be considered somewhat colorful or offensive to some. I realize that's not really a big deal for most, but it's worth mentioning. You can view a video demo of Frets on Fire after the jump (note, as the game does, the demo includes a couple of potentially offensive words).
