Fantasia Sango Mysteria

Fantasia Sango Mysteria (幻想三國誌－天元異事錄) launched on January 10, 2023, and operates as a live-service RPG with gacha mechanics, rotating limited-time summoning banners, in-game currency purchases, seasonal events, and login reward cycles. Throughout 2023, the developer shipped frequent updates including new story chapters, side stories, new characters via limited-time gacha pools, new gameplay systems, and ongoing balance adjustments. The final main story chapter (the concluding chapter) shipped on October 25, 2023. On January 17, 2024, the developer made a significant structural change: the game was converted from its original format to an "online single-player" version to lower the barrier to completion and reduce time-gating. Importantly, the developer explicitly stated in that announcement that the game "will remain open long-term" (《幻想三國誌 天元異世錄》會長期持續開放) and committed to irregular ongoing updates. This January 2024 update itself introduced new gacha pools (including permanent element-specific pools), new story replay features, adjusted monetization, and new in-game events — all hallmarks of an ongoing live-service operation. The game's structure — gacha summoning mechanics, purchasable currency (玉簡/字簡), monetized convenience bundles, rotating limited-time character banners, and the developer's explicit commitment to keeping the game running long-term — establishes this as a live-service title by design. A July 2025 promotional post confirms the developer and game remain active as part of USERJOY's 30th anniversary celebration.
