I wish I could add more, but what the other two posts said mostly stole my thunder. The first time i ever hit it was when the ride opened at Disneyland and I was captivated by it, and each successive time I've found it I've had my kicks. I even took it far enough when pinball really crapped out in my area (back west) I went and got a vpinmame version of it just to scratch the itch and I do beg for it when they do votes with Pinball Arcade too. The funny thing is I have this immortally crappy luck with pinball as it always seems to find some elastic way to hit the side drains for me on nearly any table...yet on Indy that one I can earn the free credit and post a damn good score on it. The thing is I wouldn't call it easy, it takes time, I don't just hit everything in a row with the rules, but I can sustain it which means a lot. Sure it helps it's my favorite fictional movie character and movie franchise too, but only to a point since I was definitely not sold on the Stern table design anywhere near as much as this one.
I just hope they can do a back room deal to get the Indy tables and the Star Wars ones through some Disney contractual shenanigans sooner than later on Pinball Arcade. With SW making a huge come back and Indy slated to show up as well reborn too it would make sense for appearances sake.
