Activision published Guitar Hero a few years ago for the PS2, which allowed people to pretend they could play real guitar. They did this by plugging in a fancy guitar controller modeled after the Gibson SG, and programming the "notes" for a bunch of songs that the player has to hit to play the note. Ubisoft is doing something very similar, with an entirely different style of guitar, and for the Nintendo DS. Gamers, by pressing the right button on the D pad and strumming with the stylus, can play a set of unannounced songs. Free play mode allows gamers to invent their own songs, which can be used to propose to the girl of your dreams in the nerdiest way possible.
