Summary: If you're familiar with the Guitar Hero/Rock Band series, Guitar Hero: World Tour is more of the same. This time there's lots more songs and some new features that were probably good in theory, but not well executed. That being said, this is still a great game and it's lots of fun.
Summary: If you really want a World Tour I would recommend Rock Band or Rock Band 2. To me the sound is a lot better. Here it often seems muffled by Crowd Noise. Navigating around also seems slower though I can't say I timed it and compared. I prefer Rock Band but this is great too.
