Quoted from MikeS:I don't think Ultraman is a big enough theme to financially justify a dedicated release. It's through economies of scale that it's even possible that we see it released as a game. Metallica and GOTG are AAA licenses. 95% of the pinball market didn't even know what Ultraman was until it was announced. I still think it will be an instant sellout though because 500 games Worldwide is nothing and people are hungry for new pinball machines!
95% of the pinball market didn't even know what Rick and Morty was until it was announced and look at how well that did. Ultraman is huge in the anime and the Japanese culture. Ultraman literally started the Super Sentai(Power Rangers) franchise. Spooky could sell thousands of games just in the Japanese market alone.
