Graphics: 4.25/5 Looking better than Guitar Hero III at least. The graphics look cleaner, and the animations are really good. There is still "clipping" though, which is somewhat annoying, but the game looks solid. The venues are also very nicely done.
Sound: 4.25/5 The soundtrack is pretty good in this one. Despite its name, GH:A doesn't have tracks EXCLUSIVELY from Aerosmith. There are some songs by Joe Perry ( Guitarist of Aerosmith ) The Clash, Stone Temple Pilots, among other bands. Still, most of the game does have Aerosmith tracks from back in the seventies to today.
Control: 4/5 Figures - you will likely notice a lot of these guitar expert tracks are made strictly to make them more difficult. It doesn't work, but you'll know what I mean when you see them. A lot of the songs, mostly earlier ones, have a lot of chord hopping, and other songs also have green + orange chords and just a lot of fret presses you would likely not see in a game made by Harmonix. Still, some of the charts are actually super fun. The main riff of "Walk This Way" is easy, but very fun to play.
Fun: 4.25/5 It's hard to say if this game's worth buying. If you are a HUGE Aerosmith nut, you've probably already bought it since it's been out for ~2 months. If you're not that big of an Aerosmith fan, it's better that you rent it. I beat the game in just about one sitting, five starring every song on expert except for one bonus song all in one attempt. The game is easy - quite a bit easier than Guitar Hero III. The achievements are also more reasonable in this game as well as opposed to Guitar Hero III which had some really bogus ones. I highly recommend this as a rental, whether you like Aerosmith or not, for the achievement points if you're a SCOREWHORE, or just for fun if you really like Guitar Hero.
4/5 ( You just likely won't be coming back to this game after you play each song through once or twice unless you really like Aerosmith. )
