List of music games that allow you to play more than 2 guitar controllers.
I Googled high and low for any online topic about this, and never was able to find one. So I am hoping this post will help others.
So far the list below are the only games I found that will allow you to play more than 2 guitar controllers simultaneously in multiplayer mode (3 to up to 4 guitars). So if you have more than two guitars and you have some friends or family over, well, you can trust that the game list below will not let you down.
