My god, what a game. I've owned mine for 15 years or so. *Many* pins came and went during those years. Sometimes I don't play it for months. But I get addicted again right away when I start playing it after a long time. It's still my favorite game. Nothing in pinball beats finishing Khan.
Just came back from an amazing game on it, improving my previous GC (which had been there for years) by about a billion. It all started as a casual game after a day of hard work. I'm still trembling right now. Woohoo!
