An awsome rythym/music game if you can handle the difficlulty!
Graphics: One look at this game and you would think that it had pretty decent graphics for the Wii, not a graphical powerhouse. One look at the Xbox 360 version, however, and you would feel slapped in the face. It looks a lot better but all in all, it doesn't matter for this type of game really.
Sound: This game has been praised as the best music track in the series, and rightly so. This has so many great songs in it, and most of it is original recording from the bands themselves. Of course, not all songs can be winners ("Hit Me With Your Best Shot" is so bad, they mock it in the in-game tutorial) and some of the songs are censored, so you'll be wondering why there is so much dead space in Gallow's "In The Belly Of A Shark"
Gameplay: Even though Harmonix didn't work on Guitar Hero 3, Neversoft has done an admiral job of capturing that classic feel. Although, the timing to hit the notes is a lot more forgiving this time around, they make up for it by ratcheting up the games overall difficulty to near insane levels! This is not a game for a casual gamer to pick up and play.
Local Multiplayer: This is one catagory that Guitar Hero seems to be lacking in, it never really feels like you are playing with someone, just beside them in co-op career mode. Thankfully, the competitive serves up a lot more satisfying stuff. My one beef with it is that you can get a higher percent and still lose and if you mess up and Player 2 doesn't, your done for.
Online: Yes the online capabilities that every Guitar Hero fan has been dreaming of has finally arrived, and it's pretty good too. All the options that you can do locally, you can do online. I never experienced any lag either, the kiss of death for such a timing oriented game.
Overall: This is the Guitar Hero that you have been waiting for, it is the only one for the Wii and I highly recommend it to anyone who is even the slightest bit interested. However, there is one problem, with the shadow of Rockband for the Wii looming over us in just two months (at the time of this review), you might want to spend your well earned cash on Rockband instead of this if you are more multiplayer focused. There is just one more piece of advice that I must depart you with, two wrongs don't make a right, but three rights make a left.
