One of the main issues I have with the Cleopatra backglass change is that the artwork is not really interrupted on the EM but with the SS one of the score windows cuts into the lion.
When you look at the system 1 games the displays are in the same position from game to game, obviuously for some sort of standarisation and cost reduction, unfortunately this sometimes interfered with the artwork.
This must have been frustrating for the artist working on these machines.
The other manufacturers didn't seem too worried about having to move the score displays around.
