An FMV visual novel that uses its absurd baby-in-a-dystopia premise to actually say something sharp about AI-run social hierarchies - if you can stomach the mature detours along the way.

My first instinct when I saw the premise was to dismiss this as low-effort novelty bait. A parallel world where an all-powerful AI called the Sovereign Brain ranks every citizen by measured intelligence, and you land in it classified as a one-year-old infant despite having a full adult body - adopted by two characters, Xiaoxiao and Lingling, who are themselves labelled "low intelligence" despite clearly being anything but. That setup, once you stop laughing, turns out to carry genuine satirical weight about algorithmic authority, class stratification, and who gets to decide what intelligence even means. Mountain and Sea Studio have been making live-action FMV games for a while now, with titles like Superscout and Underworld Island in their back catalogue, and that production pipeline shows. The live-action footage is competent, the cast is watchable, and the sci-fi dystopia framing gives the usually casual-leaning FMV format an unusual amount of thematic muscle to flex. The core loop is straightforward for anyone who has played an interactive fiction title before: you watch scenes, make branching choices, and the narrative forks accordingly. What keeps it from feeling flat is the intelligence-test mechanic, where the Sovereign Brain evaluates your in-world learning and hands out "Reward Drops" - a small progression hook that ties the story's central conceit directly to player action rather than leaving it as pure background lore. The choice-driven structure leads to multiple endings, and the divergence between paths is substantial enough to justify a second playthrough if you want to pull on different threads. That said, this is not a game with a strategy layer or a resource economy. If you are coming in expecting the simulation depth the genre tags suggest, you will find a visual novel with light RPG framing, not a systems-heavy experience. The "Simulation" and "Strategy" labels on storefronts are generous. The mature content warning is real and worth flagging plainly: the game includes partial nudity, sexual references, and alcohol use woven into the narrative. That is a deliberate tonal choice rather than incidental - the world Mountain and Sea have built uses those elements to underline the power imbalances between your Monarch-ranked character and the people around you. Whether that lands as meaningful provocation or uncomfortable fan-service depends on your tolerance for that kind of material, and reasonable players will end up on opposite sides of that line. First-timers to the studio's work should go in with clear expectations. On the technical side, the game shipped with some reported bugs at launch that appear to have been addressed in subsequent patches. It runs on Windows only, with no Steam Deck support confirmed, and localisation covers nine languages including English, Japanese, and both Chinese variants - solid range for an indie FMV title. Community reception on Steam sits in the "Mostly Positive" band from several hundred reviews, which for a niche live-action game from a small Chinese studio is a legitimate endorsement. The absence of any critical press coverage means you are relying entirely on player consensus here, and that consensus is cautiously approving rather than enthusiastic. If you are a fan of FMV interactive fiction with a dystopian sci-fi backbone and you want something that at least attempts a point beyond its provocative surface, this delivers that in a lean, focused package. It is not a strategy game in any meaningful sense, and anyone hunting deep decision trees or systemic complexity should look elsewhere. But as a branching narrative with an unusually sharp social premise and a willingness to commit to its own absurdist logic, it earns its place on the wishlist of anyone who burned through Immortality or the Her Story back catalogue and wants something with a bit more genre flavour.
