The backgrounds might as well be people skating half pipes instead of your character playing the guitar. I mean Im still getting GH3, but still...
The setlist for GH3 is absolutely rubbish apart from two songs i like. The series has done the exact same thing for 3 years. The "boss battle" system is dumb. And to be honest, who looks at the graphics on GH2 that much? Your playing it! Aslong as it doesnt make you want to puke and looks reasonably good, then its fine. The new characters? I'd rather make my own =)
