It's a great game, but if I could do it over, I wouldn't have ordered. I had the money set aside for Kingpin (riiiiiiiight), but could have bought a Tron LE for $5k in June of 2011. I could have spent two+ years playing that, sold it for more than a NIB WOZ and bought WOZ now. Plus, I'd have the extra $1900 available (nevertheless whatever over the price of a WOZ the Tron sold for). My feelings aren't necessarily WOZ-centric though. I think I'd pass on any NIB until the code and bugs are fixed.
On top of all of that, I became a father to twins in March 2013, so pinball playing time is scarce. My WOZ and Metallica get played about every two weeks at the moment. Not nearly enough to justify over $10k sitting around in my house. When I ordered WOZ, my time and finances were in a much different place. If I had known in Jan 2011 where I'd be now, there's no way I would have bit.
Again, great game, and if everyone had my point of view, WOZ wouldn't exist at all, so I'm very glad JJP pulled it off and raised the bar for the entire industry.
