Games include a store-management title similar to Overcooked, a Minecraft-like survival game with crafting and zombies, a bone-collecting wolf game, and a cat-following exploration game. The author notes the model handled 3D assets, sound effects, and mechanics accurately from a single prompt, used only a small fraction of session credits, and suggests non-technical users, including children, could now build playable 3D game prototypes without coding skills. He also mentions people combining Opus with Blender MCP for higher-quality 3D models and building deployable multiplayer games in hours instead of months. ## Full article daily.dev links to this article rather than hosting it.
