Guitar Hero III is nothing less than amaing. Everyone should seriously consider giving this game a look.
Just take a look at Guitar Hero 3's tracklist. These songs are not only fun, but they are great to listen to while your playing. The songlist was deffinetly one of Guitar Hero 2's main problems. Which in this case, is no problem here for Guitar Hero 3.
If you've noticed, quite a few songs are pretty heavy. Most of those are seen in the last few venues. Which is where the difficulty really gets hard.This is probably where most of the complains about the game have been. And there is really not much to say about this hear besides the game is just really hard. Like most people, I started playing Guitar Hero 2 when it first released for the Xbox 360, like most people, I started on Easy and worked my way up to the hardest mode. So I pretty much already knew how to do some of the hardest parts of solo's. So for me, beating Expert in a few days really wasn't that hard. But for the that dont know if they should get the game because it has a reputation now for being so hard, should just get it. Take your time, and practice. A LOT.
As for the Guitar goes, the buttons feel better, it looks cooler, and it just feels great. The only addition to it that I dont like too much, is the whammy bar, it seems a bit stiff when you try moving it sideways, but it's not that big of a deal. So if you weren't big on the Xplorer, the Les Paul is the way to go.
Overall, Guitar Hero 3 is a great game, addicting, and satisfying when you nail all the notes in a solo. Which to every beginner, you'll get better sooner and faster then you think. So just go get the game!
