There are the few extras in the "Vault." With the money you earned through the career, you can go into the shop and buy extra guitars, finishes, and extra characters. Extra songs to play in Quick Play that didn’t make it into the career and full videos of Aerosmith can also be bought in the shop. The videos themselves are worth a look at if you a fan of the band.
Some of the problems that lie with Guitar Hero: Aerosmith is the fact that it’s not a real update, not the step forward in the series. It’s only a spin off, but still, a couple new modes or features would have seen this off the “cash in” people may tend to see it as. Not being able to play any song from the get go for Quick Play is still an issue that needs to be addressed, instead of having to go through the entire career to unlock them. One huge problem I have with this game is the song choices that have been made: being a fan, I expected to been able to play the likes of "Dude Looks Like a Lady," "Cryin’," "Crazy," "Amazing," and "Don’t Want to Miss a Thing" are just some of the tracks that have been bizarrely left out.
All in all, this is an Aerosmith fan’s ultimate dream, being able to rock out to "Dream On" and "Walk This Way," but for everyone else, it’s a skip. Wait for the proper update to the franchise, Guitar Hero: World Tour, if you are on the fence about buying and not to sure to waste you’re money on it; Guitar Hero 3 will keep you busy in till number four.
