Keep in mind that there are two dubs for almost all of the original Showa series (1954-1975) Godzilla films. Toho's International cut almost always had a terrible dub. As you stated, some of the voices were laughable. The American cut almost always made a new dub. The two versions had a different title as well... most of the time. One of the ways you can tell the difference between which version you are watching is to watch the opening credits and see what company is releasing the movie. If it's AIP (American International Pictures) then it's the American cut. There were other companies other than AIP that released Godzilla films. If you see the 'Toho' logo at the start, it's probably going to be the International version with a terrible dub. The movies were also changed. Only the first 3, 'Godzilla', 'Godzilla Raids Again' and 'King Kong vs. Godzilla' had substantially different cuts. The other films had minor cuts or slight changes.

I'm not really sure what you can do about modding the building. Everyone has been saying that it is a modding opportunity but it is all metal and moves up
and down. How can you put a facade on it? If you do that, it won't fit through the hole in the playfield. The bridge looks like there should be no issue.

These are the movies from the era of which this game is made. Keep in mind that they are using 10 of the 15 listed here.

Just look a few posts above....

Trolling as usual, I really hope your life isn't that empty that you need to do this...

Cuz selling every machine you can produce is fighting for scraps... brilliant... Maybe I should start a pinball company and sell every game I can produce like Spooky and JJP so I can fight for scraps...

While Stern deserves all the credit in the world for "keeping the light on for pinball", they haven't exactly pushed the hobby forward. They clearly needed JJP to show them the way for pricing and features people wanted and they need Spooky to teach them customer service. A top notch company would never have allowed the competition that they have allowed. Just the fact that all of these tiny companies have emerged tells you that their business model is not top notch. No company their size in a technology driven business should have the competition they do with the massive advantages that they have. They may one day be the last man standing but they better hope that JJP never gets it's act together and learns how to produce in volume and doesn't pay Keith Elwin more money or they might find themselves fighting for scraps.

That said I hope that everyone makes great pinball machines and everyone stays in business and everyone makes lots of money.
