Just because it focuses on Aerosmith, doesn't mean that there aren't songs on there from other bands. When I first heard it was coming out, I wasn't going to get it. I mean yeah, I really like Aerosmith, but the idea of not having anything else to play just wasn't very appealing. Luckily though, they were smart enough to predict people like me and so they added songs from bands that have some connection to Aerosmith. That means we also have songs like Cheap Trick's "The Dream Police", Ted Nugent's "Cat Scratch Fever", and my personal favorite, Joan Jett's "I Hate Myself For Loving You" to choose from.
Graphically, the characters that you play with look a lot like the ones from Guitar Hero: Rocks the 80's. Izzy Sparks is especially 80's glam looking. So much so that when you play with him for the first time, you'll achieve the "Dude looks like a lady" achievement. There is also a new character or two available for you to play with. All the characters have a second outfit available by default and several more that you can buy later on.
