Guitar Hero is one of those 'Why didn't anyone think of this before?' kind of games, so it's no surprise that the series' popularity eventually led it to the Mac. Aspyr Media licensed Guitar Hero III and published it for Windows and Mac at the beginning of this year, and now they've followed that up with the Aerosmith edition, which is a standalone game, as opposed to being an expansion pack.

The gameplay in Guitar Hero: Aerosmith is the same as the original: Watch the notes cascade down the screen, hold your finger(s) on the proper fret(s), and strike the strum bar as the notes reach the bottom. Hit the star-shaped ones to build up your star power, which you unleash by tilting your plastic guitar up. Sorry, no bonus points for doing Pete Townsend windmills or lighting your guitar on fire like Jim Hendrix did.

If you're an Aerosmith fan, you'll be in heaven with this game; if not, you may start to long for the diversity of Guitar Hero III. Of the game's 41 songs, 29 are Aerosmith tunes, while the rest come from groups that have either played with the band or who inspired them. The storyline charts the band's history from the early days to their gig at Super Bowl XXXV and induction into the Rock 'n' Roll Hall of Fame, complete with new video interviews with the members. As in previous Guitar Hero games, you unlock venues when you successfully complete enough songs there, and you can also unlock characters, guitars, songs, and other stuff along the way. Even when you've unlocked something other than a venue, however, you still need to buy it with the cash you earn from playing gigs.

Four difficulty levels let you work your way up to working all five fret buttons at a frantic pace. I've watched experienced Guitar Hero players tackle the toughest difficulty and score big points -- if you paid me to play the game eight hours a day, I still don't think I could ever get there. I enjoy the first two difficulty levels, however, and I appreciate the fact that those other two difficulty levels sit there and taunt me.

The multi-player action from Guitar Hero III also makes an encore appearance here. You can head online and watch others humiliate you with their plastic guitar skills. Luckily for uncoordinated people like me, there's an option to jam with another player; one plays bass and the other plays guitar. You could arrange a virtual Woodstock.

If you bought the original Guitar Hero III bundle with guitar, you can pick up Guitar Hero: Aerosmith by itself, although Aspyr also offers a bundle that includes both games with the guitar.
