Walking away from a machine because you won is not that common in pinball. It's one of the things I like about pingolf. In one player games, you always lose...ball drains at some point and your game is over. In competitive match play, it's much more common that you lose or walk off plunge than it is that you come from behind on your final ball to take the lead and can walk away.
Yeah, multiball is fun...but hitting a shot and being able to walk away a winner is pretty rare - which makes it really satisfying. Sure, trot around the bases by playing my multiball, but the goal here was to hit the homer before my opponent.
