It's hard to argue with Guitar Hero III's place in the series canon. By going real with the songs, next-gen with the graphics and online with the gameplay, it leaves the wishlist relatively barren. At the same time, it's not delivering us much new on the gameplay front, and in fact lags a bit in terms of smart strumming mechanics. Neversoft would do well to remember that the game doesn't play itself, and we need to be challenged/satisfied with how and what we shred.
Let us critics dissect the nuances of this game. As a player, it's your job to pick up a guitar, select a song, and have a rockin' good time. Guitar Hero is still the best of the best when it comes to music and party games, and Rock Band is going to have its work cut out for itself to justify its bigger pricetag and later release.
