Im from Old School. My design would be single layered playfield. The machines actual size and shape would resemble what the Gottlieb Wedge Heads looked like. Them, I would do something cheerful, like a Summer Time activity. I would call it "Cushman Resort" A popular resort that is located in Washington state on lake Cushman. Artwork on backglass would show the way the resort looked in the late 60s. Kids playing around on the dock, swinging out on the rope swings, etc. Just people lounging around the lakefront having summer time fun
