Just like it says, would you pledge if your dream theme was crowdfunded so that the manufacturer could get all of the assets to make the most immersive, amazing playing & best theme integrated pinball experience ever?
Think Harry Potter, The Matrix, JAWS, Die Hard, Predator, Masters of The Universe, Bill & Ted, Legend of Zelda and <insert your dream theme here>
EDIT: Crowdfunding by a proven & reputable pinball manufacturer (JJP, Stern, AP, Spooky, CGC)
