Guitar Hero On Tour is a handheld entry in the wildly popular Guitar Hero series that released on the Nintendo DS. There are only a few things you can really say about this game: (1) the integration of the Guitar Hero gameplay to a handheld was impressive for the time and the game makes great use of the touchpad and Gameboy slot thanks to the required Guitar Grip accessory; (2) The song selection was fine, but was missing classic tracks. (3) hand cramps.
