Well none of my friends like GH3 or any rhythm game, so I was wondering about the private coop matches. Is it like actually going through the list of songs as if you would if your friend was right next to you? or is is just like a quick match you play 3 songs and that's it? If its not like that I would like to get some achievements for doing coop so would anyone wanna play GH3. I could play bass if you really wanted guitar.
