When did Guitar Hero become the new 'Madden', offering track updates with each passing iteration rather than innovation? With rumors of Metallica and Van Halen branded titles on the way, get used to it. If you have played any Guitar Hero titles at this point, you know exactly what to expect. The mechanics, gameplay, graphics, and characters remain the same from Guitar Hero III. If you have not yet tried out the series, Aerosmith is not where you want to start. True, it plays well enough, but it is not representative of what is so great about the franchise. While previous versions give you a solid amount of variety, Aerosmith, thanks to its narrow focus, does not come close to the breadth of material offered in past titles, and does not allow gamers to play downloadable tracks.
