A potentially unwanted effect is that the Win/Mac icons will be hidden. If you game on Windows, the loss of the windows icon is probably irrelevant, since essentially all games on GOG run on Win systems already. However, you may want to bring the Mac icon back; if so, just remove ".icon-mac, " from the style (it's only in one place; be sure to cleanly delete from the period to the comma). I needed to do this because otherwise there's not enough space to bring back the ratings bar.

Rating color code:

0.0-1.9 = black
2.0-2.9 = red
3.0-3.9 = pink
4.0-4.1 = yellow
4.2-4.4 = yellow green
4.5-4.7 = dark green
4.8-5.0 = bright green
