I know I'm a little late to the party when saying this (and a little embarrassed to say that), but I just played a Champion Pub and thought that the interactive jump rope toy was pretty brilliant. I'm not a huge fan of the theme, but it was well done, and worked really well in my opinion.
It got me thinking, I've probably overlooked a boatload of neat little things they've included in pinball machines lately. What's your favorite toy or gimmick that they've used in a pinball machine?
