I’m not what you would call a major gamer, but I’ve played the console version of “Guitar Hero: World Tour,” and I didn’t get booed off the stage every time. So that makes me an expert, right? When you’re playing “Guitar Hero” on a mobile phone, the most important thing to bear in mind is that you’re playing it on your phone. That means, mainly, that you’re not going to get the console experience. However, Hands-On Mobile has put forth a respectable effort at replicating the experience in a portable format.
