I got the limited edition Guitar Hero DS Lite with Guitar Hero: On Tour (DS).
I would rate it 8/10
It is not the greatest Guitar Hero game, but at least it is portable. It is not as realistic as the PS2, PS3, XBOX360,and Wii Guitar Heroes because you do not actually have a guitar in your hand; you have a DS in your hand. And the bad part is that you only have four frets on it, not five. The only good part in having only four frets is that it is easier for some people. But having a pick as a stylus is pretty cool. And the other bad part in Guitar Hero: On Tour is that Slash is not in it. Slash one of the best characters in Guitar Hero. That is all I have to say about it.
It is still really fun playing it though :D
