Tired of being tied to your TV when you're shredding to the Ramones? Or perhaps you can't bring yourself to buy a big plastic guitar. Then, my man, Guitar Hero: On Tour was made for you. Everyone's favorite party game has been downsized to the palm of your hand. Of course, you may've heard about it by now—350,000 have been sold since it was released on June 22. And with just a month out on the road, Nintendo just announced plans for a follow-up: Guitar Hero: On Tour Decades. It's supposed to feature song-sharing, a microphone and, we suspect, a set list that spans a few generations. But until then, this one will do. That is, unless someone finds a way to make it into an iPhone app. $50, (with free shipping) at Amazon.
