First, I've played the crap out of it in the Pinball Arcade app. But that's only useful for learning the rules and hearing the call outs. They try to get the feel of real pinball, but that's a hard thing to do.
I've been fortunate to play a few real ones though. There's one at the Pinball Museum in Las Vegas, but it has seen better days, at least when I was there which was a little over a year ago. I played a couple at California Extreme last year. There's also one that I've played a couple of times here in San Francisco at a place called Free Gold Watch.
There is something about this pin that is right up my alley. Maybe it is because I am such a Monty Python fan and it plays into that humor a lot. It may not be the deepest of the deep games, but there are plenty of goals to keep you occupied. The rules are easy to pick up and it's all pretty straightforward. The call outs and music just make it such a fun experience. I don't think I could ever get tired of destroying the castle.
That is why I have put a deposit down on a MMRLE. I have to own one and am happy to have the opportunity to get a NIB with all the updated tech and from what it sounds like, perhaps even fixes to some of the issues with the original machines. I hope it all goes well being an early adopter.
