I'm finding with the new artwork system I have to chop down the overlays and bezels and such. BattleZone is a perfect example; the art is lovely, but just a tiny rectangle in the center is left for the actual game! I hacked up the art until there's just a small strip of the overlay around the edges, just enough to get the flavor of it....
In my mind, the most useful purpose for the bezel art is to fill up the blank space on the sides of vertical games played on a horizontal monitor.
