The handheld version of Guitar Hero never struck me as a great idea, despite Activision's best efforts to make it work with their crazy-arse glove accessory.
But my Kotaku colleague Tracey claims it's pretty damn good. She's actually been playing it a lot on the train recently, but given the state of Sydney trains I'm not sure if that should be taken as a ringing endorsement.
Still, David Jones - of all places - have Guitar Hero On Tour for DS on sale for $19.95 right now, until September 13. I'm not entirely convinced, but at twenty bucks it seems like a reasonable risk to take.
And, hey, if it sucks, you know who to blame.
