Yakyuken ULTIMATE – A New Generation of UGC Game Creation

Hello everyone! My name is Shark Nobuo, an indie game developer based in Japan. I started my development journey in early 2026, and my project is "Yakyuken ULTIMATE."
(Note: I am a Japanese native and use translation tools to communicate in English. If any nuances feel off or if you have questions, please feel free to ask!)
"Yakyuken" is a traditional Japanese game based on Rock-Paper-Scissors. In my project, it serves as a core mechanic where winning rounds allows players to unlock new outfits and visual expressions for their characters.
However, Yakyuken ULTIMATE is much more than that. Our core concept is "The Joy of Game Creation."
This project is a flexible UGC (User-Generated Content) engine that transforms players into creators. You can import your own characters (created with AI or other tools), add custom stages, and build unique stories.
We have now reached Version 0.55. The core engine is stable, and the media loading system is ready.
Attached is a preview of our "School Festival" stage, featuring our main characters: Hikari (left) and Kurumi (right).
Updates will be posted here regularly, so please follow us and join the journey of building the future of UGC gaming!
Thank you for your support!

Hello! I am artist Theobrobine. I mainly create nsfw animations. The main activity in Patreon will be used as an early access place to post full-size, full-resolution animations and project data before other social networking sites such as Pixiv. Project data in clip format will be posted only to Patreon and FANBOX. Your support will be used for the cost of living and equipment to continue the illustration activities.
