Simon Willison 实测 Opus 5.5：四款氛围编程游戏可玩，RTS 已开源

2026/10/28 23:20

核心观察：Simon Willison 发文称，2026 年 10 月对“氛围编程游戏”是一个新节点；他用 Claude Opus 5.5 在数周内做出四款自己真正愿意玩的浏览器游戏，且单个项目人工投入均未超过四小时，更多时间由 Claude Code 自行迭代。
能力变化：他认为 Opus 5.5 在 3D 建模、音乐生成与游戏设计三项上明显提升；此前模型能做出“看起来像游戏”的 demo，但难点是玩法是否有趣。他给 Battle Drones 的提示词是“Make it a LOT more fun”，模型据此重做后具备可玩性。
四个项目：Tree Appreciator 用普通 Claude 聊天一次生成；Emberwick 是可完成约 15 分钟剧情的 3D 奇幻 RPG；Battle Drones 是 Command & Conquer 式 RTS，已有 2–4 人联机、回放、七张地图、随机地图生成器与 LLM 对战模式；Pumpkin Farmer 是农场模拟，Opus 5.5 Ultracode 消耗数百万 token、近两天构建。
开源与社区分叉：Battle Drones 以 Apache 2.0 许可发布；Gabriel Turpin 随后发布分叉 Panache，将其改造成 1900 年代法国 Belle Époque 蒸汽朋克设定，加入新模型、音乐与动画开场。这说明模型生成的项目已能进入开源协作与二次创作流程。
行业影响：文章指出，氛围编程游戏同时覆盖 AI 生成代码、美术、音乐、对话与游戏设计，可能加剧玩家社区对 AI 素材的抵触，也可能把游戏开发门槛降到更广人群。作者预计会出现类似编程领域的分化：一部分玩家拒绝此类游戏，另一部分接受新创作者进入。
边界：这是作者个人实验与观察，不是基准测试；他称 GPT-6 Astra 也能构建游戏，但其“趣味感”暂不及 Opus 5.5，并预计 OpenAI 年底前可能追上。四款游戏均为 HTML/JavaScript、静态托管，复杂商业游戏、团队协作与长期维护未覆盖。 🔗 Simon Willison's Weblog | Battle Drones 说明 | Panache 分叉

Screenshot of a web game called Tree Appreciator, a spot-the-difference puzzle showing two side-by-side 3D renders of the same leafy green oak on a grassy hill at golden hour, with orange low-poly hills and a hazy sky behind and pale rocks in the grass. The left tree (Fig. i) has a small brown-and-o

Inside, warm candlelight falls on wooden floorboards: a stone fireplace with a figure in a red armchair on a red rug, a blue armchair with an orange cat on

A huge green troll lies asleep on a straw bed at top right, surrounded by scattered bones and skulls. The cave also holds a small round pool ring
