An unusual example of a successful YouTuber collaboration game, Mamon King was co-funded by Yoshinama, who invested roughly $160k USD out of his own pocket to produce it.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The game ended up becoming a viral hit, selling over 60,000 copies in its first week and allowing Yoshinama to <a href=\"https:\/\/automaton-media.com\/en\/news\/japanese-streamer-who-spent-160k-usd-to-make-his-dream-game-breaks-even-in-just-a-month-plans-to-invest-everything-into-next-game\/\" target=\"_blank\" rel=\"noreferrer noopener\">fully recoup his investment in just a month<\/a>. \u00a0<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Recently, the YouTuber made a new video update on the status of the game and its sales, announcing that Mamon King would be getting a physical release for the Nintendo Switch 2, coming to Japan on October 8.<\/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\u3089\u534a\u5e74\u3001\u3068\u3093\u3067\u3082\u306a\u3044\u3053\u3068\u304c\u8d77\u304d\u3066\u3044\u307e\u3059\u3002\" width=\"1160\" height=\"653\" src=\"https:\/\/www.youtube.com\/embed\/HdNW2EtGt-w?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 class=\"wp-block-paragraph\">In the video, Yoshinama also reveals that Japan\u2019s video game giant Koei Tecmo is partially involved in the distribution of Mamon King\u2019s Switch 2 release. Among many famous series like Nioh, Ninja Gaiden and Atelier, Koei Tecmo has also worked on the Monster Rancher franchise, which served as a major inspiration for Mamon King.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cIsn\u2019t that crazy? I\u2019m extremely honored. It really makes me feel as if they officially recognized [Mamon King] as a work inspired by Monster Rancher,\u201d Yoshinama said.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">As for the future of Mamon King, Yoshinama explained that the game is steadily on its way to selling 90,000 copies. Aside from recouping the full $160k USD investment, the game also generated a profit of about $12.6k USD, which Yoshinama plans to invest in his next work.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Back in January, Yoshinama <a href=\"https:\/\/automaton-media.com\/en\/news\/japanese-streamer-who-spent-160k-usd-to-make-his-dream-game-breaks-even-in-just-a-month-plans-to-invest-everything-into-next-game\/\" target=\"_blank\" rel=\"noreferrer noopener\">expressed his wishes<\/a> to start the production of his next game in around a year and a half from then, aiming to announce it after around three years. Apparently, Yoshinama already has a clear idea of what the next game is going to be, and in his words, it will be \u201cway better and more fleshed out\u201d than Mamon King. Considering that he now has enough funding to prop the development of a new game, it will be interesting to see how a potential new Mamon King sequel, or an entirely new IP, will shape up going forward.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Related articles: <a href=\"https:\/\/automaton-media.com\/en\/news\/monster-rancher-inspired-indie-passion-project-mamon-king-tops-steam-charts-in-japan\/\" target=\"_blank\" rel=\"noreferrer noopener\"><strong>Monster Rancher-inspired indie passion project Mamon King tops Steam charts in Japan\u00a0<\/strong><\/a><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong><a href=\"https:\/\/automaton-media.com\/en\/news\/japanese-streamer-who-spent-160k-to-make-his-dream-game-thinking-i-dont-care-if-it-doesnt-sell-hits-60000-copies-in-under-ten-days\/\" target=\"_blank\" rel=\"noreferrer noopener\">Japanese streamer who\u00a0spent\u00a0$160k\u00a0to make\u00a0his dream game\u00a0thinking \u201cI don\u2019t care if it doesn\u2019t sell\u201d hits 60,000 copies in under ten days\u00a0<\/a><\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n","protected":false},"excerpt":{"rendered":"<p>The Nintendo Switch 2 edition of Yoshinama&#8217;s Mamon King is set to receive a physical release on October 8 in Japan. <\/p>\n","protected":false},"author":79,"featured_media":54679,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_gspb_post_css":"","autoblue_enabled":true,"autoblue_custom_message":"","autoblue_shares":[{"did":"did:plc:uzrrhkfyjrfdsynj2voztcf2","date":"2026-08-13T08:38:50+00:00","uri":"at:\/\/did:plc:uzrrhkfyjrfdsynj2voztcf2\/app.bsky.feed.post\/3msxal3apnm2p","response":"{\"uri\":\"at:\/\/did:plc:uzrrhkfyjrfdsynj2voztcf2\/app.bsky.feed.post\/3msxal3apnm2p\",\"cid\":\"bafyreigg5jahy76f2oupcaea53ggsjsltqm7cyhyf62isw7ayrpbqbp6yi\",\"commit\":{\"cid\":\"bafyreigw3x6w4t23laeoyuysingdxbq4jzbtpoakdh7drqvhm6koagzlua\",\"rev\":\"3msxal3awie2p\"},\"validationStatus\":\"valid\"}"}],"autoblue_post_url":"","autoblue_publish_document":false,"footnotes":""},"categories":[62,3],"tags":[39,17],"class_list":["post-70949","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-indie-games","category-news","tag-indie-games","tag-japan-related-news"],"blocksy_meta":{"styles_descriptor":{"styles":{"desktop":"","tablet":"","mobile":""},"google_fonts":[],"version":7}},"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.2 -
