If you like Aerosmith you will like this game. Otherwise you will hate it.
The best thing about this game is how the guitar reacts to the notes and the person playing it. They have done something new to make it way easier and hammer ons and pull off glide as the slightest touch. I did like that. I played through the entire setlist on expert with no problems what so ever. I never even left yellow at my worst.
So if you like aerosmith try it otherwise rent it for the easy achievements then return it the next day.
