How much do the guitar hero games cost?

I don't know what they cost and I want to buy it/them. And one more thing... all three work on Play Station 3 right?

I think the gutair is 69.99 and the game is 40 or 50 dollars. I am just guessing

its like $50
and yeahh but you have to buy different guitars for three, like you cant use a guitar hero one/two guitar with a three, it doesnt work.

They are $50.00 each and yes they do work on Play Station 3.

if you want to buy one of the games and a guitar+ manual and all that junk in that one box they sell it in, it is about 130 dollars. the game alone is 50 dollars, and a guitar control alone is about 40 dollars.
