I, like, just got Guitar Hero about a week ago, and I've been playing that a lot. Graphics suck pretty hard. I don't think Harmonix has done, like, a single thing to improve the graphics in their games since they released the original "Frequency", and they haven't changed the gameplay at all, so this pretty much plays the same as all their other games, just with one track instead of, like, five or eight. Also, about half the songs on it are pretty much bragging rights for the company's staff, and the rest are almost all decently covered but still weird sounding vocally.
Not what I was hoping for, but better than it really had to be considering.
