It just does. Guitar Hero III for Playstation 3 has finally given people a reason to purchase a Playstation 3. Sony thought that having blu-ray would do it; it turns out people would rather play a plastic guitar than watch a movie in HD.
Guitar Hero III is all that and then some. Everyone in the family can play and the game is extremely addictive. The price may be a tad bit high (I'm sure it will come down eventually) but the Guitar Hero franchise is here to stay, just like American Idol. Hey, is there a Guitar Hero Idol on the way?
