| AI judgment deepseek-flash | Partial AI · solid production, medium confidenceReasoningThe disclosure lists AI for in-game visual elements and pre-rendered sequences, so some shipped assets are AI-generated. It also covers supporting work like UI, localization, and code. Real on-location filming and a single release point to genuine production effort rather than volume. Against: Only one review so far, so player reception is barely tested; the developer has just one game, so no pattern of mass releases. |
