No, actually, it's more expensive that Rock Band... Rock Band is only $170, but GH4 is $200, as far as I know.
Can't decide whether I will get Rock Band when it comes out or wait for GH4. GH4's song creation and the ability to freestyle with drums, as well as the raised cymbals, that's going to be pretty sweet... but it's going to be a real long time before that comes out. Don't know if I can wait with Rock Band out and all.
The reason there isnt an overwhelming response to this, is because the thread was already made. And as for the game, I cannot wait... The instruction manual would make good TP. lol as you can tell i despise GH
