Quoted from accidental:How about I500 where if you hop a launched ball over to the left flipper and fire it up the right ramp for a secret skill shot?
Either the plunger control isn't very important, which means it's just using the flippers to make a particular shot at the beginning of the game, or if the plunger control is essential, it's a 2-step process which to me is a super skill shot... But I wouldn't count a shot as a super skill if there isn't a regular skill shot also available.
I'm picky but if a game gives me a chance to do a feat using only plunger control (plus nudging maybe), it's a skill shot, but if the plunger only lets me set up a shot to make from the flippers, the game has no skill shot.
I'm even iffy on a machine like Gorgar, BH, or BK2K where my only plunge control is which lane I hit. The award there is for completing the lanes, not just making a particular shot. There's no advantage to doing it on the plunge, versus getting the ball through a lane later in the ball.
