I play it. Not on the "hot streak" right now, as I play it for a while, then off, then on, etc etc. I love it, and by far is one of the best games that I own IMO.
I have GH3, used for the Wii, and I have beat the game on medium and easy. I cannot reach the dang orange button to save my life.

The speed can be as fast as it wants, but if you put an orange in, it messes me up completley.
I love to play "The Devil Went Down to Georgia," "Cliffs of Dover," "Stricken," "Reptillia," "Radio Song" (

), "Through the Fire and Flames"... a lot actually. Those are the only ones that come to mind right now.
