I always liked the Playboy pinball machine.

I worked at an arcade while I was going to school in central PA. There are lots of Amish folks in PA and (I'm not sure how the rules work) at some point when they are teenagers they have the opportunity to leave the farm and go out into the world. Anyway, whenever any Amish teens showed up at my work all they would play was Playboy pinball and all of the driving games.

I think we even used the "PG-13" versions of the artwork, no exposed breasts...
