Wife's favorites are Cirqus Voltaire, Spiderman, WOZ, Fish Tales, and although she didn't like it at first really was sad after I sold Pinbot after 7 years. She seems to like our latest acquisition, Pinball Magic.
On the opposite end she hated the Centaur I brought home and still makes fun of it as the ugliest game we've ever owned. And as far as theme, none of the Playboy pins will ever come home and actually I'm fine with that.
