You plug it in to your own guitar and play it like Guitar Hero. My son is going to but it and i'll give my review later. Wikipedia Rocksmith is a music video game produced by Ubisoft similar to Guitar Hero, Rock Band, Power Gig: Rise of the SixString and Offbeat Guitarist, and based on the technology in Guitar Rising. The game's main focus is the unique feature that allows players to plug in virtually any guitar and play. It will be released on three platforms: Microsoft Windows, PlayStation 3 and Xbox 360.
