Hi there!
Let me get straight to the topic.
As of right now, the Player Rating "icon" (if you can even call it that) is the little box next to the number of plays.
My idea here is to make so games rated 100-90 would have a light green background, 89-50 the background that it is right now, 49-25 a yellow color and 24-0 to have a red background. The point is to just make it a little bit nicer.
