I just read this uses the "AirG" a sort of accessory with fret buttons that you click on your Wiimote. Could be "not bad", but I think people that want to play a guitar game also want to ROCK OUT! Hmmmwell, if Maroon 5 is the rockiest thing in there I'm not interested.
When do developers learn that a good music games cannot go without a good solid tracklist (preferably containing the original versions)
