Everyone should own a Guitar Hero game. If you haven't played it yet, you really don't know what you're missing. The music rocks. Playing with a guitar shaped controller rocks. Jamming with a friend rocks. Did we mention that the game rocks? Everything from the presentation to the gameplay in Guitar Hero II is universally appealing. If you haven't already played Guitar Hero II on PS2, this is a must own game. Even if you already have done all of this before, you may yet find a reason to grab the Xbox 360 re-release. With reworked graphics, sound, new songs, downloadable content and more, this is easily the best Guitar Hero game yet. Introductions are in order.
