I remember when the first Guitar Hero launched for the PS2 in early 2006, it was a ground-breaking concept. Since then, there have been far too many iterations of the game on virtually every device and platform conceivable. And now you can get your own personal copy of the latest Guitar Hero (Warriors of Rock) in the palm of your hand for the low price of $2.99 from the Amazon Appstore. The game costs $7.99 in the Amazon Market.
If you have never played or heard of Guitar Hero, it is a "rhythm music video game" where you have to match notes of (usually) rock songs by hitting the colourful buttons that appear on your screen.
