I picked that she is indifferent, although it isn't that simple...
When she is stressed about space or the house gets messy, she hates it and wishes we didn't have them. Note -- the house has 7 pins in it, all downstairs, and they aren't the cause of the mess. Our complete lack of closets is.
When she is having friends over, she loves them and tells people about how we've got a bunch of 'em. That's usually in the summer when I can set up a dozen in the garage too, and my wife will invite over her friends to have a fire in the backyard and have a pinball competition. It's surreal.
The other times, she doesn't really care one way or another usually. Once in a while, she'll say something totally out of left field that will leave me wondering what is going on, like when I told her I was buying a Twilight Zone recently, she was really excited about the idea and suggested I buy it sooner than later. Other times, she'll half-jokingly offer to sell my games to people for $20.
My son has started to really get into pinball -- he just turned two, and he loves "Jar Jar Pinball" (aka Star Wars Episode I), and that makes my wife like it more too.
When she plays, she is surprisingly good. I wish she'd play more, but I can't complain as long as she lets me play / fix the machines
