Produced by the famous Japanese gaming YouTuber <a href=\"https:\/\/www.youtube.com\/channel\/UCEnkd5D-53MDGpgpiQRbUqw\" target=\"_blank\" rel=\"noreferrer noopener\">Yoshinama<\/a>, who invested roughly $160k USD out of his own pocket into the project, Mamon King continues to do well on Windows and Nintendo Switch, with a PlayStation 5 version on the way alongside plans for other platforms.<\/p>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"\u300e\u30de\u30e2\u30f3\u30ad\u30f3\u30b0\u300f\u767a\u58f2\u304b\u30891\u30ab\u6708\uff01\u885d\u6483\u306e\u58f2\u308a\u4e0a\u3052\u3078\u3002\" width=\"1160\" height=\"653\" src=\"https:\/\/www.youtube.com\/embed\/ynObv7CtLr4?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe>\n<\/div><\/figure>\n\n\n\n<p>According to Yoshinama\u2019s recent video update, he has already managed to recoup his $160k USD investment and is planning to immediately put all of it into his next project. As he explains, all of the recouped money, as well as future Mamon King sales, will be going straight into the production of his second game. \u201cAs long as I have the money, I want to keep making games until I die,\u201d says Yoshinama.&nbsp;<\/p>\n\n\n\n<p>Concerning his next game, Yoshinama says that he can\u2019t disclose any details just yet, but is hoping to start production in around a year and a half from now. If everything goes as planned, he expects to announce the new game in about three and a half years. Apparently, Yoshinama already has a clear idea of what the next game is going to be, and according to his words, it will be \u201cway better and more fleshed out\u201d than Mamon King, with more funding to prop it up. However, it is still unclear whether the next game will be connected to Mamon King or take on a completely different concept.&nbsp;<\/p>\n\n\n\n<p>On a related note, in an interview with <a href=\"https:\/\/automaton-media.com\/articles\/interviewsjp\/mamonking-20251205-369678\/\" target=\"_blank\" rel=\"noreferrer noopener\">AUTOMATON JAPAN<\/a> which was published before the game\u2019s release, Yoshinama mentions wanting to work on a sequel should the first one be successful:<\/p>\n\n\n\n<p>\u201cIf this one becomes a huge success, I&#8217;d really love to make Mamon King 2. I know it&#8217;s incredibly stupid to think about this when the first one isn&#8217;t even out yet and hasn&#8217;t received any reviews. But the ideas just keep coming\u2014there are so many things we couldn&#8217;t implement this time that I&#8217;m sure would make it even more fun.\u201d<\/p>\n\n\n\n<p>However, we will have to wait at least a couple of years before we find out if the next project turns out to be a Mamon King sequel, or something completely different.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"672\" height=\"378\" sizes=\"auto, (max-width: 672px) 100vw, 672px\" src=\"https:\/\/automaton-media.com\/en\/wp-content\/uploads\/2026\/01\/20260130-563310001.jpg\" alt=\"Mamon King gameplay. \" class=\"wp-image-56333\" srcset=\"https:\/\/automaton-media.com\/en\/wp-content\/uploads\/2026\/01\/20260130-563310001.jpg 672w, https:\/\/automaton-media.com\/en\/wp-content\/uploads\/2026\/01\/20260130-563310001-380x214.jpg 380w\" \/><\/figure>\n\n\n\n<p>Mamon King first drew attention thanks to <a href=\"https:\/\/automaton-media.com\/articles\/interviewsjp\/mamonking-20251128-368668\/\" target=\"_blank\" rel=\"noreferrer noopener\">Yoshinama\u2019s hefty funding and involvement<\/a>, and many tuned in to follow the success story of an avid video game fan trying to make his dream game come true no matter what.
