Yuanzai World

Yuanzai World is a mobile adventure game in which the story, characters and worlds are generated by AI rather than following a fixed script. Players travel through fantasy and other settings with a companion character called Yuanzai, talk to characters, and change how events unfold. The site gives the name as a codename and offers English, Simplified Chinese and Traditional Chinese. A player can start a world from a single idea described in natural language, whether fantasy, science fiction, modern or ancient, and the AI turns it into a playable setting that can later be rewritten and expanded. Conversations with non player characters are open ended instead of multiple choice, with voice interaction and real time communication. Characters are described as remembering tone, choices and relationships, and as responding to personality and background. Player decisions can shift character fates, the balance between factions and mission goals. Yuanzai itself helps organize clues, sort out the current situation, suggest ideas at turning points and generate items. Players can also share a world seed with friends. The game is available on the App Store for iPhone and iPad (iOS 13 and above) and on Google Play for Android 7 and above. The website does not publish pricing, and does not say whether the game is free, paid or includes purchases.
