    gnome-games doesn't support relocatable .gnome2 directory (Bug 613634)
    
    libgnome has an environment variable to support relocating the .gnome2
    directory.
    
    We (Red Hat) have a customer that wants to make use of this feature.
    
    gnome-games currently hard codes ~/.gnome2 instead of looking at the
    environment variable.
