Your Rome game folder does not have any icons on it, if you bought the game using genuine DVD this folder will have a custom folder image. I think you might be using a pirated version of the game. As you also have SerialBox (a serial code piracy tool) installed I think we can safely say that your problem is because you don't own a genuine version of the game.
So the solution is to buy a copy from an Apple store or the Feral website.
