I used to have this mode on but have it off now as it scares the shit outta me when i'm watching tv or something and i have forgotten that i have left my games on

I agree. Gilligan made me jump every time that theme song started!
Makes sense in an arcade/pub though, and surely wouldn't be hard to code for by the designers. Start a petition if you want it, but not for home - too distracting, and I know they are there anyway ( because my kids always leave unplayed balls on them so they tell me to "hurry up" or " little more action here" or similar!
